  • REUPLOAD - Sorry folks, but TH-cam decided to fill all the blank spaces with static in the last go-round. Call me picky, but I just couldn't stand it so here's a second go.
    If you had commented on the 1st upload - THANKS! I wish there was a way to preserve that kind of thing here.
    I built a loop antenna designed to boost the reception of AM broadcast radio. It's simple construction, requiring only some PVC pipe, speaker wire, and a variable capacitor scrounged from an old radio.
    The results are pretty good, even through the weather decided not to cooperate on filming day.
    Here's the link to the on-line loop calculation I used:

    Thanks Matt. very nice design! I've tried building AM Loops without much success. but no one ever mentioned that I had to place the radio in the loop. For the record, I am definitely and old guy and love radio. especially AM. there's just SO much good stuff there. decades ago, I worked third shift and listened to Coast 2 Coast AM w/ Art Bell. Those were to good ol' days man. Thanks again, all the best, Charlie

      These days about 1/2 the AM band is taken up by COAST overnight. WHAS-840 is 50KW (day and night) and can be heard in most of the country - but Kentucky is college basketball country and the post game shows can preempt the COAST broadcast on many nights. Or, sometimes there are technical problems... I am building this to get the show from a dozen or more other stations just in case one might be down. Hopefully some of these stations are still broadcasting in HD too! Not to mention if your town came under some sort of an apocalypse! :-O Then a battery operated radio and this antenna could save your life!

    With only my 1947 tube radio with only two 1 meter copper electrical wires hanging out of it as a antenna! I am fascinated by it.

    Wonderful and fun video. 👍 As a teenager in the 60s we loved the Clear Channel 50,000 watt stations (or 250,000 watt station XERF in Mexico) we listened to in the evenings on handheld transistor radios, it was practically like shortwave because in San Diego we could get a bunch of stations across the country up to the Mississippi River. It was amazing to be in San Diego to hear a station in Chicago or New Orleans....no loop antenna required.

    Bought a commercial little medium wave loop some time ago. They attach two wires to the cap and bring the end via a phono plug into the receiver. Works from roundabout 500kHz up to about 3.8Mhz. Neat construction your loop Matt, thanks for the video!!!

    I love pvc loop antennas too and every time time I watch this video I LOL at the section where you wind it. I use a sharpie and a ruler and then a hacksaw to slot the pvc. I built a 2 footer as well using #22 magnetwire and 1/2 inch PVC. Great as a signal booster and a good local crystal set too. I also resurrected an older 4 foot version built with 1 inch PVC and widened the slots and wound it with #15 magnet wire. It is a ridiculous signal booster and a decent crystal radio set. I used balanced armature IEMs as earphones and matching transformers with a germanium diode and tinned the turns so I could just use an alligator clip to select the best place for listening. So far I have bagged 22 clear channel and regional stations at night using it as a crystal set.That is only 5 nights so far for a couple hours each night. Enjoyed the video. Loops are magic and heavy gauge wire is worth it. Best wishes!!!

    I think the best reason to use a loop antenna like this is mainly the ability to rotate the loop to null out an unwanted station that's causing interference.

      +Eric's garage Broadcast TV is alive and well. We ditched cable 6 years ago. Lot's of Internet based content for sure, but there is an antenna for the TV as well, and we get almost 40 stations. The other interesting thing is that over-the-air content is not compressed nearly as much as cable or satellite. The HD picture is beautiful compared to what we used to have on cable. When people come over to visit they ask if I have a 4K set :)

    I did one that is 4x4 feet with 4 turns. It worked quite well.
    My method involved no drilling. or glue
    I suggest others copy the idea. Imagine you are holding some PVC pipe in your left hand wit a T on top of it.
    You pass the wire on the side close to you below the T
    loop it around the T and to behind the pipe in your hand.
    The result is a wire that doesn't want to slip off the T.
    This is how I did the 4 corners of the frame.
    It works fine.

    I built the same 2 foot PVC frame antenna but I used 42 turns at 4 inches wide tuned to 150 khz to 1700 khz I used a hack saw to cut out around 35 notches each , yes some wires do overlap and are paired up to make the 42 turns needed to tune down to 150 khz. It actually works really good on LW and AM despite the hasty wire spacings. I want to make a larger 6 foot version with better properly spaced wires.

    I built one on the bedroom wall around a small shelf. Used long wood screws with the thread valleys setting both the spacing and the anchor points for the wire. Didn't need antenna rotation since the distant station I liked listening to was broadside of the wall. The antenna is still there.

    • @DavidEsp1
      @DavidEsp1 ปีที่แล้ว

      As explained by Matt in reply to other comments, the directionality of the loop is broadside-null. To receive a station at best signal, the loop should be such that the station is in the same plane as itself. Because it works by phase difference between its two vertical sides.

  • @AZStarYT
    @AZStarYT 2 ปีที่แล้ว

    Another loop antenna builder used a technique to save time (and cost of material) by using 4 conductor phone wire, soldering the ends to get 4 loops for a single length of cable. Even more turns can be made using older network cable (i.e. cat 3) that can be found pretty cheap at thrift stores, now that people are upgrading to cat 5e or 6.

    It’s easier if you drill the holes, then take the band saw and cut a slot from outside to the hole. Then wind the wire around.
    I’m in Alabama and listen to stations in Maine, New York and up in Canada with a similar setup.
    I use a ham radio because modern cheap AM radios don’t cut it like the old radios did pre 1970.

    Don't know what direction you are from KYW but would have liked to see you turn 90 degrees. I did that the other night (just the radio, not using a loop) and was able to null out KYW and its 50kW and tune in WQMV in west Tennessee, 317 miles away running four watts. For all the faults of mediumwave ya gotta love the directionality.

  • @DavidEsp1
    @DavidEsp1 ปีที่แล้ว

    For output to coax (say) to the terminals of a radio at some distance, you could add a secondary pickup mini-loop, untuned, e.g. of a couple of turns, in the same plane as the main loop. Needn't be of same diameter as main loop, and needn't be centred. Having said that, on my own 1 foot sides loop my secondary loop is wound in same V-slots as the main loop (all turns are in same single V-slot at the end of each arm. Not saying this is optimal (I have no idea) but it works. I imagine though, with long coax capacitance, a smaller pick-up loop might be advisable, to reduce its impact on the tuning of the main look.

  • @Systorable
    @Systorable 5 ปีที่แล้ว +2

    Building an AM radio antenna myself and have a couple questions. First, let me fill you in on background info. I have some thicker wire that's single strand I got from Lowe's. It's insulated, so there's no problem with the loops touching. The one problem could be thickness. It's 18 gauge, if I remember, and that may be too thick. The first loop will be rather far from the last loop, so the loose ends will have to close in fairly far to the capacitor.
    Question: Is this wire too thick?
    Question: Will the loose ends coming in to the capacitor cut across the field in such a way it'll interfere with the signal?
    Question: Can I use a 5 gallon bucket to make this antenna? I'll wrap the wire around the outside and tape it down with clear packing tape. I''ll put the capacitor inside the center of the bucket, mounted on a piece of PVC pipe. I'll put the radio by the capacitor. Will this work?

    Thanks Matt for a good project, There is a problem finding a 360pf vairiable capacitor now days!, the small ones used in portable radios are 200pf which will restrict the lower frequencies to about 650khz. The solution is to use two of those in parallel or increase the turns to 15 from 11.

    • @kensmith5694

    @dennisjones8991 ปีที่แล้ว

    If you have the ability to, a vertical antenna that is at least 1/4 wavelength at the LOWEST frequency you intend to listen to is ideal. If you really want to listen to DX stations, provide a ground plane and a earth ground to your radio. Am stations in north america use vertical polarization, and use a 1/4 wave long/high tower to broadcast from. This can also be used for amateur radio operators for transmitting using a matching device, although a ground plane IS REQUIRED for transmitting. The vertical antenna is usable from the lowest frequency you have it cut for up through 30 Mhz as a receiving antenna as well just by hooking the wire directly to the antenna terminal, just like for AM radio reception. If you want it to work better in the horizontal plane, have the wire at an angle of about 45 degrees from the vertical plane. Always disconnect the antenna and ground it during an electrical storm, preferably OUTSIDE the building.

    Also, I have a GE Super Radio III, great for DX on MW anyway. I am going to attach the feed line to the radio, the other to ground. I assume that the capacitor in this particular radio that is made for this will be enough to handle the tuning. I am not sure what kind of cap is in there but it has wide and narrow band, and auto freq control.

    Forgive me for being totally oblivious to any of this. I don't fully understand what you were doing with the wire. You start in the middle? What are you doing, threading an end through all the bottom holes, and then working upward?
    So, one end of the wire connects to the leg of that capacitor thing, and the other one the body?? I didn't see where it connected to the body.
    I'll watch it again, but didn't fully get that part.

  • @stevesybesma
    @stevesybesma 4 ปีที่แล้ว

    Question, when you drilled the holes for the wire to go through, I would think they would have to have been offset all the way around, no? My plan was to create four PVC pipes over two feet long to put between two 6' square frames and then start by drilling a hole in the first PVC pipe 1 inch in, the second one 1.25 inches in, the third one 1.5 inches in, and finally the fourth one 1.75 inches in (and from THAT first hole on each pipe one inch apart) so that the spacing between each loop remains perfect on all four sides through the entire thing when doing the wiring.

    Hi Matt, very nice and easy to follow instructions here.
    One little newb question though, as far as i could see here you just placed the radio inside the loop.
    so I guess any existing antenna should be placed inside or in relation to this ? Not actually connected to the radio?

    • @MattHeere
      @MattHeere  6 ปีที่แล้ว

      That's correct. The only reason I put the whole radio inside my loop is because it's own antenna is internal

    Matt you mention a couple times about making a smaller loop to put inside to allow this to be used on a radio without an internal antenna. Can you give a little more detail on that small loop. I have an old stereo that has a very good receiver, but just 2 wire connections for AM Radio and I want to greatly improve my AM reception. What does small mean? How many loops? Do I hook the two ends of the lop to my stereo? Do I ground it? Etc. Many Thanks

    How would you add a loop to connect the radio that has an antenna connection?

      What channel range are you interested in? UHF or VHF? The Gray-Hoverman antenna is an outstanding antenna. I have built 2 or 3 versions of them and they all performed like a champ on weak UHF signals. The last version I built is known as the gold standard.

      @@Bruce_Wayne35 I am interested in the VHF and UHF. The VHF is because I live in a location where there are still a few channels that I would like to get and UHF all the way to 52 channel. I got what I need for the antenna build and am going to start. Not sure what is the gold standard ??? Nice to hear from you Sir. v

      @@victoryfirst2878 It's what the members of the Digital Home Canada discussion board/inventors chose to call it. The gold standard version was the highest gain UHF version of the Gray-Hoverman antenna. It covers channels 14 to 51 and has usable gain beyond that a bit, so it would still work great on 52. They're easy to build. Even a sloppy build will amaze you with good performance. A double-bay version will have around 16 dbi gain.

    How mu make such a loop work both on LW and MW? I had to make 2 separate ones because my 36 turns one will only work on LW and the one with 8 on MW.

    Hey, thanks for the very informative video. I have one suggestion. Many of us have no need for the PVC glue stuff after we have completed this project. I think it would be cheaper and better to use screws and holes drilled in the PVC to hold it together securely.
    I made one out of wood, and I find that when it's not used, it takes up room. It would be really interesting to make one that could be collapsed to a small space. I thought about using one of the collapsible umbrellas for the frame. I wonder of that would work okay and how long it would last. Thanks.

    • @MattHeere
      @MattHeere  6 ปีที่แล้ว +1

      Thanks! Some good ideas there. Really any glue will work. Superglue is the best substitute for the PVC cement, but even good old Elmers white glue would be fine.
      As for collapsible: I like the idea. Best bet is likely to make the "X" frame with a pin between two legs so that it would fold flat. You do need to be careful about introducing metal into the build though. It can throw off the calculations for the loop.

    Would a larger loop increase signal strength? Would more windings increase signal strength. Is there any best distance between the windings? This video is excellently done and based on your answers to my questions, I plan on building one. First time I have really gone out on a limb about projects like these and said that. But you instill confidence! Thanks!

    • @MattHeere
      @MattHeere  5 ปีที่แล้ว

      Larger loops do "catch" more signal, but in practice you have to go much bigger to make a noticeable difference. The number of turns and the spacing are related, and more isn't better. They have to be the right mix for the loop to tune to the frequency you want. The calculator in the video description is the best way to experiment with different combinations.

    For Long waves (down to about 150khz ) it has to be about 32 inch edge, about 30 turns of wire (100meters), around 475 pF or more capacitor. It works fine. But in Europe there are only 4 stations transmitting on Long waves.
