You might not be ‘professional’ but you are an expert.
What a beautiful piece of engineering ! Thoughtfully engineered and executed. A huge credit to you my friend. Cheers from OZ 🇦🇺
One little tip on the little tractor (I have one just like it)... Extend that backhoe bucket as far out as possible for some counter weight, and poke the teeth into the ground for some more holding. It's sometimes just enough to make all the difference in preventing the tractor from moving.
Marc I know I commented previously about this being the best video series out there for this application. Well by watching this series several times and consulting with a friend who is much better at math than I. I'm happy to report in late October last year we got my 60 foot tower with a 10 foot mast on top up and working. It has withstood some 90 km winds and a couple of winter blizzards so far without issue. Not worried about summer as the trees will fill in and create a wind break for most of the tower. Can not thank you enough for taking the time to do these videos.
A very interesting series of videos on a great engineering solution. 👍 Hats off to you and anyone who has the knowledge and expertise to design, build and instal projects like this. I'm with you on the "no climbing" approach. I retired 2 years ago after 40+ years of climbing as a linesman but now find it quite a chore as age takes it's toll😂.
Thanks for the positive feedback Phil. I really enjoy using this system and it was a great fun project to design and build. Marc.
Great tower. Might I suggest filling the bucket with dirt as a counter weight. It will help greatly.
Good suggestion. Thanks for the comment.
What an amazing setup! Thanks for sharing!
What an amazing project. This is the nicest tilting tower I’ve seen. I wish I could buy a kit with all the parts for it. Great job.
Thanks for the kind words. I am glad that you enjoyed the video. I also agree that a quality tilting tower kit would be great (I would have bought one), but I already spent the past 30 years running a small engineering business and I am not that interested in starting another one. lol . Take care. Marc VE3BOE
@@marcinmetcalfe595 By chance do you have a set of plans you would be will to sell for this set up. In the next few years I will be building a shop in some property. I would love to build your same set up. I am a carpenter so much I can do except for the welding I would have to hire out. Including the tilting beam antenna with the other antennas you use. In my opinion this is really the ideal set up. I also like the clear to sprayed on the aluminum. Can you tell me what product you used? Where did you buy the tower?
I don’t have any plans. Most of the construction details etc., can be seen in the videos and found in replies to comments found in the three video series. The clear paint is Rustoleum clear. Good luck with your project.
That is a work of art
Great video and thank you for sharing. Im doing a similar project this year but I have opted for a tilt/telescopic mast that i will need to build from scratch as they dont have them in the Philippines.
Great build , maybe a couple of holes drilled through the base to allow the water to escape , great workmanship .
There are a few holes. With all the other technical aspects of the design, that was the least of my worries. lol. Thanks for watching.
@marcinmetcalfe595, thanks for this video. It gave a bunch of good info and inspiration for our tilt up project that finally got set in place yesterday. 73!
very nice landscape at the end. good job
I have seen great antenna tower work.
감사합니다
very cool design and setup. Had I seen this before I did mine I would've done mine like yours. It looks safer than mine.
Thanks Mike. Had I seen this video before I would have done things differently as well. LOL
Amazing set up 73s
great vid. W O W
Beautiful
got that right!
Great setup - thanks for sharing !
Interesting video👍
Thanks for sharing 🙏👍😊
Hopefully we can meet on the band 73s VK6HY also on freeband lol 😁🙏👍
Thanks for the kind words Arnold. The Amateur Radio community is such a considerate and kind one. I am glad to be a part of it. 73s to you as well.
Thanks for the informative video. I am gearing up for something similar here - 4S7AB Sri Lanka
I am glad that you found this video informative and that it might assist you in developing your own setup. I remember how helpful other TH-camr videos were when I was designing mine. Your QRZ page is very interesting. You are certainly a very accomplished Amateur. I laughed at your reference to "little QRM machines". I now have second generation "QRM machines" here, but now that QRM goes away after a few hours or a few days. LOL. Take care and good luck with your project.
beautiful design. only recommendation i can make would be to make and install a cover for your base so you don't have standing water in your tilt base. other than that i am 110% jealous of your setup. does this tower design allow for manually climbing the tower to perform work or is it solely meant for doing work when in the down position?
Thanks for your comments Rick. I did drill a few holes in the base for standing water drainage but I think I need a few more. With regards to the tower’s climbability, the original manufacturer of the tower states that it is climbable if installed according to their specifications. My titling mechanism falls outside of their specified design. My design intent was to never have to climb it.
I know it’s been a while but……the falling tower anchor could be anchored with a deadman
Hard to tell in the video, but it looks like the cables from your "falling derrick" are not at equal tension when under load (the cables attached to the tower). Should not all of them be of equal tension when pulling?
Great design
Wow, you’re living in paradise. Very nice setup you have there. Did you remove the wasps nest or did you forgive them for liking your antenna tower more than you do and leave them be?
Thanks for your interest. Yes I feel very fortunate to live here. It was not active when it was in the video so I removed it. I get lots of different kinds of nests around here.
Where did you purchase the pulleys? Amazing video. This is inspiring me to convert our 48 foot tower to be a tilting one...
Great video!!! Beautiful country!!! KD2QMJ
Amazing
good view of FLAT EARTH!
Nice Work
Thanks.
Ótimo trabalho gualidade total bazuka Foz do Iguaçu pr Brasil
Obrigado
Very nice 👍
fantastic, 73 de PY7DJ
Brilliant setup. Could a guy use hydraulic rams to raise and lower the tower rather than the cable set up you have? Regarding the Tremclad Clear, did you brush or spray the tower. It’s so clean and new looking. I ask as I’m just getting into the hobby and looking for a used tower to purchase. There a few around for sale close by me heights being 40’, 56’ and 96 feet. My concern is I don’t know if they are capable of being strong enough to handle the action of lowering and raising with out buckling or snapping at the pulling/lowering point, is you’re tower built from a heavier grade of steel so as not have that happen. Thanks 73
I would guess that there are many other methods to raise and lower a tower like this. It is simply a matter of knowing how to design and implement them properly and safely. I can't speak tp the suitability of other towers. The tower I am using was not intended to be used in this manner by the manufacturer. The lower segment of the tower in my project is reinforced. This is stated in my part 1 video.
Dream Tower ,antennas and location🙏
Very nice. Did you add drain holes to the base plate?
Very professional job. I am amazed in your attention to detail. I see is previous comments that the mast is a 20' aluminum one. Can you tell me the ID and wall thickness? I am planning a mast location of similar length and antenna array. Also, what was the length of the falling derrick in relation to your mast height? It seemed to work very well. 73's K5OOL
Thanks for your nice comments Chris. My falling derrick is 16 feet in length. I am looking into my records for the exact spec on the mast. I remember being very specific about that and I had to have it special ordered by my local shop. I will repost when I find it.
The Aluminum mast has a wall thickness of 1/4 inch and an outer diameter of 2 inches.
Wow, nice everything. How tall is the whole setup to the vertical at the top?
The tower is 56’ tall. The mast extends 12’ above the top of the tower where the VHFUHF vertical is mounted. Thanks for your interest.
Might some weights hanging (at an appropriate length) on another wire off the guy wire(s) opposite the gin pole make a balance so the tower doesn't slam down and wobble so badly. Others do this and have even made a perfectly balanced tower pivot using the counterwight to offset the weight of the ginpole, etc. They literally hand lower it into its final resting place an inch at a time. This also eliminates the need for a solid brace between the tower and the ginpole. See th-cam.com/video/i1apgY3Gw5U/w-d-xo.html
Thanks for this awesome informative video about your tower and the yagi antennas! One quick question, would the Comet antenna, I believe you said yours is the CA-52HB4, work very good for the 160 - 162 MHz range. I'm having trouble finding a yagi within that programmed range.
Thanks for your nice comments Joseph. The antenna I believe you are referring to is the 13 element Cushcraft 13B2 and it is designed to operate from 140 to 148 Mhz. I may have mistakenly called it a comet in my video. I don’t believe it would be effective in the frequency range you asked about.
Ah okay, thank you so much! Once again amazing set up with the tower!
Can this be converted into small cell phone tower, thx.
Please do a shack video!
how long is your mast? I see you have three separate beam antennas on it.
The mast is 20’ long. Each antenna is mounted four feet apart. The first antenna is a Hygain Explorer 14 (with 40m) about 1 foot up from the tower top bearing, then four feet up to the Cushcratf 5 element A505S for 6m, then another four feet up to the Cushcraft 13B2 13 element for 2m, then finally an additional four feet up to a Comet GP6 for 2m and 70cm. That leaves approx 7 feet from the top bearing down to the rotor. The Mast is aluminum. Hopes this helps.
And with regards to the antennas, there is also an Alpha Delta DX A 1/4 wave sloper (160m, 80m, and 40m) located a few feet below the Epxlorer 14 beam. This gives me total coverage on the tower of 160m, 80m, 40m, 20m, 15m, 10m, 6m, 2m, and 70 cm. It’s relatively easy to add antennas to a tower when you can easily bring it down to the ground. Hats off to those who climb to do this. I hope your project is working out well for you.
@@marcinmetcalfe595 20 ft of alum mast pipe must’ve been extremely expensive but worth it. I’m looking at the same tower locally that has never been installed. I would only use it for tilt as well. I missed the first two parts but I will watch them. I’m currently in the city but somewhat looking in rural areas for a home and a few acres. Very hard to come by at the moment. I’m also very curious on how your 40m add on compares to your 40m wire “alpha delta”? Thanks for the inspiration. 73 jay
The aluminum mast was actually not that expensive. I seem to recall around $200? . I couldn’t tell the difference between the wire 40m and the Explorer add on element so I ended up removing the 40m add-on and restoring the Explorer 14 to its original design. The 40m add on is structurally very weak and, in my opinion, a bit too much for this size of antenna. That’s why I removed it. I would not recommend it.
@@marcinmetcalfe595 thank you very much for the feedback. I’ve noticed that with 40m trapped dipoles also. If you can recall the aluminum pipe size and number, that would be great. I think metal depot is where I looked before. I’ve been using gas pipe and it’s extremely heavy and causes massive wind load up top. I would definitely like to do it right this time. Btw I’ve found 40m delta loops do well in a sloper or vertical plane. Fed 75ohm rg11 stub.
Marc, What the mfg & part number of the lightning arrestors? What wattage rating? Coax 259?
I used the PolyPhaser PPR-IS-50UX-C0. They are the flange mount type with SO-239 female connectors. The specs state 2000 watts. They make many variants. I used LMR400 Ultraflex for all antennas.
Ta heck with the the tower,,I like the garage...beautiful setup Marc,,as others have said,,I'm about to do something similar here in Honey Harbour north of Barrie.How tall is your tower and what is the size of the winch?....Gene..VE3IJD
Thanks Gene. My tower is 56’ tall with 12’ of mast extending above it for the antennas. The winch I am using is a 12,000 lb unit. It is actually overkill considering I am using it in a double line pull configuration. You’ll have to do the math on your final setup for your required size. Best wishes to you from Metcalfe south of Ottawa. VE3BOE
@@marcinmetcalfe595 Cheers Marc for that outstanding setup you do have there. Congratulations. Got a question about your tower, what brand is it? Looks like a Wade DMXHD, made there in Ontario, isn't? I'm about to mount one 40 feets of that same brand ( Wade ). Thanks for sharing and best 73 from VA2VG.
@@6alban The tower is based on a DMX48 Heavy duty with an additional 8 foot straight section added. The mast is a 20' aluminum mast with 14' protruding from the top of the tower. The rotor mount was custom located lower than the original to provide greater stability. The stock Wade top bearing was replaced with a heavier duty Yeasu GS-065 top bearing.
Sir linear bremi 25 watts about
how do you make the hinged plate for the antennas? 73 de Ben K0BLR
I got the idea from this this gentleman’s web site, : www.glagowski.org/radio/Antennas%20Hinge%20Plate%20Boom%20Mount.htm
