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.
