When I'm mobile I use a 102" whip tuned with Icom AH-4 tuner and a IC-706mkiig. While camping I have a work in progress, I bought a Buddipole and use the IC706mkiig.

I first used the Buddipole on Field day while camping in the mountains without trying it out first, bad idea, old Murphy had his field day. I set up and fired up the radio just before field day started. I had a s9 noise level coming form the Generator, so turned it off, I then found out that the Computer to radio interface USB also caused noise on parts of the band so I disconnected it, man I wanted to use that logging program. I then had a lot of RF feedback that was giving me a false SWR reading and I adjusted the Buddipole to short. Needless to say I heard a lot of stations but had a hard time working a dozen of so stations all day.

On my next camping trip I fixed some of the problems, I bought a MFJ-269 antenna analyzer and found out it was RF feed back causing my problems with SWR, I coiled up half the coax into a 5" to 6" coil and then everything loaded up ok. On the radio interface I added some ferrite beads to the cable and now it is quite. I have bought the parts I need to filter the Generator just need time to get it done. I have also bought parts to build a balun/unun for the antenna. Work in progress, but I will get a good portable station soon. On my last camping trip I made contacts all over the US and had no problems getting operators to answer my CQ and got good signal reports. Can't wait until this new sunspot cycle kicks in.

By the way, I found a flag pole mount on the internet that you bolt to the ladder. I cannot remember the name of the outfit, but you should be able to find it through Google. It's two peice. The lower portion is for the bottom of your mast and the top is a slotted sleeve with the slot at 45 degrees or so. You simply place the mast in the top and then pivot to the vertical and insert the bottom of the mast into the base. It makes raising my 33 foot mast a snap. I think it cost around $60 and I'm sure most of that is in marketing expenses.

Default Antenna for my RV

Okay

I value the opinion of you folks and would like to get a few clues.

I upgraded to General in July....really didn't do much in HF. A little 10m, and a little 40m....not much of anything else.
I my house I have a IC706MKIIG hooked to a At-100Pro.
I think it is RFing back to it's self. A friend put the antenna wire in the attic. But I haven't been up there to look at it.

I would like to get a good screwdriver to use in the RV or maybe get another ah4 Icom tunner like I have in my pick up and use the 706 in the RV.
I live in a Condo so the HOA Nazi's frown on antennas. But I do have a UHF/VHF antenna up. and they don't say anything about it.
I was looking at the High Sierra Trailblazer set up. But that's a lot of bucks to shell out.
For what that would cost I could almost buy 2 of their Sidekick antennas. Mount one to the RV and mount the other to the pole my uhf/vhf antenna is on. and then just move the 706 between the RV and the house.

Any suggestions.

I am old school and build my own antennas. My favorite bands are 40 and 75, I am getting ready to build a very long vertical which will be a full 1/4 wave on 40. It will have a very large home made coil in the center for use on 75, optimized for the highest Q possible. It is made of .250 copper tubing and is 5" inner diameter and about 5" long. When using 75 it will also have a large capacity hat to reduce needed inductance in the coil. The base will be 2" aluminum tubing from old 2 meter beams, about 15 feet long. The part above the coil is an old CB 5/8 vertical, telescoping aluminum, around 17 feet long. The mount will be on the pinbox of my 36' fifth wheel. There is no metal in the body or roof of the trailer. It is going to be VERY narrow banded with the high Q, but highly efficient (for an RV).
