- HF Mobile whips can make great portable antennas. Maybe you already have some. A couple of single band models may cover your needs. Here we look at how to use them and the way to connect them up.

Interesting video..
Looking forward to a few more details on the Line Isolator.. 👍
Very interested in this application for mobile / portable antennas. Subscribed to your channel to watch the promised future video on counterpoises. Thanks for your work!
What a great short informative video Peter
Another great idea from a man who knows.
I used to have every Hustler Resonator for mobile ops with a TS-430. I used a CB Spring mount on the rear quarter of my 1979 Ford Wagon and a Huster mast to get the resonator(s) above the roof line. I drilled and bent a strip of Alu and mounted 2 and sometimes 3 resonators. 40 or 20 up, 17 and/or 12/10 tilted back. The tuning varied only slighty from just 1 to 2 to 3 resonators. It all worked quite well for the several 90 minute drives to/from the New Hampshire/Main coast lines for a day of Salt/Sea/Sun with the Dogs/Kids/Wiffy and once with a Siamese Cat!
Never thought of using the Hustler Resonators for Portable Ops. Great idea.
Getting HAM Functional again after a 4 year absence via Mobile/Portable Ops. Too much PowerLine/BCI noise to opperate from new QTH. This vid is a positive addition to my plans.
Thank You Sir for this and your other excellent posts.....

Thanks Peter ! My IC-705 arrived today from WS I will build this box and use the antennas as well. Cant wait to get /M with the 705 !
Hope you enjoy it! 73 Peter.
Very enjoyable, thank you for making the effort.
Paul, Many thanks. Peter
I do enjoy these videos you post.
Hi Joti, nice to hear from you. 73s Peter
Very nice concept. I usually use in portable station, 2tlt antenna and a full wave antenna in vertical position, works perfectly 25 mhz to 30mhz. 7351 and good contacts.
Hi Stephen. It's a nicely made antenna and works well. I have found that a lot of the beacons don't pick up "test" so well. Not sure if others have the same problem?
73s Peter.
good vid Peter and some great ideas there. Cheers
Nice little slant on our hobby. We need to encourage people to build more. I have used similar to the ground mounted box, they work really well on beaches. I wouldn't have bothered with the adaptor/piece of threaded bar. Just remove what is basically an elongated nut and screw the hustler straight on its place. Keep up the good work.
Hi Trevor. you are right but the reason I did it that way was so the whole mount remained rigid when swapping antennas. Thanks for your support. 73s Peter
Finished constructing mine today, was going to try to get a contact on 20 Meters, but its full of contesters! Going to try next week.
Thanks. 73s Peter
Regularly carry a tripod in the car for my telescope, excellent alternative use.
As an aside what did you use for isolation? Just curious...
Nice video... How well does do they transmit and receive set up that way?
I disagree Peter - You deserve a prize for constructing this box - It's Great.
Hi Frank. Nice comment. But my eyes are not what they once were! 73s Peter
@@watersstanton Nor are mine Peter lol. Just had my first ever contact with America today. On my End Fed Half Wave antenna I managed to get high up in a tree using lengths of pvc electrical conduit joined together with a hook on the end made from a coat hanger. From the hook I tied a short piece of rope with a home made insulator on the other end to connect the end of the antenna wire to. When I had the wire hooked on a branch I just pulled the conduit down leaving the wire up there. Pretty hard to see the wire but it is still up there even after the high winds we had lol.
Whats the part called you screw the antenna to? the one connected to the tripod ??
Ah very nice!
Thanks Peter. Especially liked those project boxes and the way you can peg them to ground (saves lugging tripod about?). Curious to know what you have found works for radials? How many, are they tuned, are they raised or just lying on ground?
Steve, a quarter wave single works. Will cover in depth in another video. 73s Peter
I always been thinking about the common mode chokes in mobile usage, I have done some small testing with a mag mount, but don't record the results, I can remember the swr was impacted, and also the metal around the ferrite (cars body)
I'm just living in the belive that peple usually don't care about common modes in mobile hf, I might be totally wrong though, but so far what I seen it's quite rare to see chokes on mobile instalations
Thanks Kristian for that info. 73s Peter.
How lossie is those antenna? Would it work for Qrpp 2 watts?
cheers Peter 73
Thank you for taking the time to make this.
If I might comment - way too many words conveying far to little information.
What’s in the box?
What length radials how many?
The ground clamps are called tent pegs. Speaking of which whilst you’re there have you considered grounding it?
Hi Graham, There is another video coming up which will deal with your questions. 73s Peter
I was thinking of using my Tarheel II on the Icom bacpac with the IC-705 when it arrives. Just figuring out counterpoise issues for 40-10m use. GTU maybe?
Hi. New video coming up dealing with counterpoise decisions. 73s Peter
Very Nice Video. You gave me a good idea for making the box. What mix Toroid did you use? Thanks and 73, KC9REN, Dean
Hi Dean, I used an old toroid I had in the junk box! I think 43 mix. 73s Peter.
Good info, thanks, I like your box with choke. What radial lengths, quarter wave I assume? More than 1 help much? 73
Elwood, yes quarter wave. There is a coming video that will answer your questions. 73s Peter.
Great video Peter, I have a few mobile antenna's purchased from your emporium! Interested to know more about the line isolator..73 Dave G8XDD
Yes please!!
Hi Dave, I will try and cover that in an upcoming video. 73s Peter
@@watersstanton Thanks Peter.
Take a look at the MFJ1979 and Chameleon Hybrid, good from 80-6M.
Hi Robbie. I believe the Chameleon is an end fed wire with 9:1 transformer? It’s OK for portable operation although the efficiency on the low bands will be low. Thanks for your input. 73s Peter
do you have a set of plans for the antenna mount. New to hame radio and I would like to try this idea
George, watch out for upcoming video. 73s Peter.
Hi I asked you about lack of reception on another video I don't know if you answered as I haven't received a notification but I like this and have whip antenna I shall try like this set up to eliminate the antenna for homebase use to see if that is the problem cheers
Lorry I am getting more mail than i can possibly but radio conditions are very poor at moment so dont panic!
@@watersstanton Cheers mate please don't see what I said as a complaint it wasn't my intention but watching the vid I thought it was another good way out of eliminating the home base antenna so will try that but at present you know how things go a bloke is right across the board for me at Peterlee which is probably 25-30 miles away I'm guessing he is running a burner on FM
Interesting video there is another antenna which is auto tune the Atas 120a
Hi Alan, good to hear from you. I am sure viewers will check this out. 73s Peter.
how do you calculate the length of the counterpoise for these antennas?
Hi there,
If you are using a single wire, you need a quarter wave on the band of operation. Google has calculators for this. But you can often get good results with several shorter radials. 73s Peter.
Where can you purchase a 3/8" male-to-male stud adaptor as featured in this video? I tried your website, but hamradiostore.co.uk/ seems to be down.
Hi Mike,
Go to a DIY outlet and buy a long 3/8" bolt. Screw on a nut and then cut the head off. Then unscrew the nut ro smooth out the saw cut. Hope that helps? 73s Peter.
Is the "line isolator" a 1:1 Balun?
Not when used at the TX end.
@@watersstanton So what is it?
Is that toroid wound 1:1?
Yes
Everything seems very weak and wobbly... you need to mount things using stronger clamps, connections, and things.
The engineering is up to the user and the conditions in which it is used.
