Default HF antenna for RVs

I have been playing with different antenna ideas for the MH for awhile. Nothing seems to work great, aside from putting a dipole up once you arrive at the campground. The dipole is usually not real easy and may not be feasible at some campgrounds.

I recently purchased a Zero Five 43' vertical (10-160) for my home QTH. It is the best vertical I have ever used. I am very happy with it.

The other day I was in QSO with a gentleman from Texas and the subject of RVing came up (yes, I suggested he join this forum). We discussed RVs and then RV antennas. While talking about antennas he mentioned that Tom from Zero Five antennas was making him a custom fold over vertical for his RV. I stated that there was nothing on his web site about mobile or RV antennas. The guy says that Tom is going to make this one custom and see how it works before trying to sell any.

I will be watching this closely because if the antenna is viable both in mounting and useage for an RV (and works as well as his vertical I have) then I will probably just have to get one!

I posted this since there has already been some discussion about RV antennas on this forum. The down side to this particular antenna as it was described to me is that it will have to be folded down while traveling (30+ feet long).

If anyone wants to take a look at the Zero Five website....here it is....

I have used an old beat up Butternut vertical with good results on my island hopping campains. I have thought about modifying one of those such that certain joints were held together with hose clamps. Then the antenna would break down into sections for transport and go back up quick, easy and still in tune. A little dab of "bulb grease" would make the sections come back apart easy.

Then there's my trusty 20m bazooka dipole. Wow. Works the world on 100 watts, the secret being when you are QTH'ed on a desireable island the DX will come to you!!

I was in the same boat as you at one time.
I wanted to use a 23' marine vertical with a tuner but it dawned on me that with that antenna fixed to my RV it could limit my parking as I would not be able to use it without the absence of trees.
Many campsites that we have had in the nearly 40 years of RVing that we have did have trees and having such an antenna was not an option in my opinion.
At one point I did have an EZ-UP tri-pod that I could move around and I had an Outbacker on it and then changed to hamsticks later.
That afforded me more mobility but then I had to set it up and take it down.
I also had to set radials out needless to say.
I also wandered about kids wandering in and around it in the campsite.
I am quite happy with my 102" whip mounted high up on my rig. It's fed by an AH-4 tuner and the FT-897D. It's out of the way except for travel. I do have to tie it down (or remove the whip) as it's mount is only 1' from the top of the rig. On the other hand it tunes 6-40 and I get good signal reports.
I can also had a length of wire to it with an alligator clip to tune more bands if I want to.
But as you well know as a ham you have to adapt.

Ken, the wire on the whip can yield some pretty impressive results. I tried that over the weekend. I clipped about 60 feet of 16 gauge onto the whip on my Jeep and the results were very impressive. Had I more time, and if I hadn't broken my radio, I'm sure I could have made a pretty good contribution to my meager DX log.

Most campers around here use the Eagle one . 80 thru 10. http://www.w8afx.com/ Is built by a local ham . I have one that I use set up in back yard.

I've been using a couple of Ham Sticks mounted atop my rear ladder on our 5'er. I have them on a quick disconnect. Working 75 and 40 meters mostly. I've had satisfactory results. I'm taking along my old Hustler antenna this next trip. I'll use the adaptor so I can mount 3 of the loading coils at once. It will keep me from having to climb the ladder everytime I want to change bands. Better for my knees as well (staying off that ladder).

Have a great day all.

Jim

I've been considering one of the KJ7U antennas, www.kj7u.com, for some time. Anyone have any experience with one on an RV?

I have seen several auto tuners, the one I have in the truck is manual similar to setting the button on a car radio set the SWR with the radio or a meter press and hold the button it remembers the turn counter setting. They are OK but due to motor drift they may not produce flat SWR but fine for while driving. I have heard mixed revues for the auto tune ones they are out there for less than $200. I took my home made screw drive ground mount with me on a trip down south and I have found it to be a fair amount better than mounting it on my pole behind the camper above the roof. I don't think I would worry about 160 with a screw driver antenna it probably would make a better heater than an antenna.

I have a home made rotating dipole that I can move the elements inside one another and be resonate on 10/12/15/and 17 this all fits on fiberglass poles up about 26'. Looks kind of silly on the back of my 17' camper but it sure works well. I also have a 40/80 meter dipole made from ladder that mounts to the poles but that really takes up a lot of real estate. If I,m some where that makes it a pain to assemble I stick the coax inside the sliding window on the truck and plug into my screw driver antenna.

My concerns and thoughts.

First I drive a 37'7" Motor home, I suspect that if you folded the 43'er at the right point and mounted it at the right point you coudl have it full length and it would lie on the roof of the MH (in a cradle) when driving quite nicely.

That's the plus

Of course do it a bit different and you could detach say 20 feet and just fold 10 over.

Now the hard part.

RADIALS. 43' verticals need a good ground radial system.. You may have an issue there.

They also suck on 75/80/160

Ham sticks seem to work OK. Mounted on ladder mounts. I guess if I RVd full time I wouldn't be happy.
