For now, consider a Buddipole setup with the tripod base - you can set it up for any of the bands, and take it with you if you need to. you may need a tuner to help out, but just a coax to coax model will do - in the $100 range. You could spring for an external auto-tuner for a few hundred more. personally, I'm delighted with the automatic internal tuners on my Icom 746Pro and Icom 703. There are some external models designed to work with the 7000.
I've considered the Buddipole and see there are mixed reviews, it seems like there are lots of fans and lots of critics, I haven't concluded whether it's a good idea or not. One negative is that you set it up for one band at a time, vs tuner + wire can work many bands at once.
The tuner (Icom AH4 is designed for long wire/random wire) would leave open a lot of room for experimentation and expansion if we move somewhere with more yard (unknown).
Thanks for the input, it helps with my own thought process. It seems like I'm favoring the tuner + random wire for now, although I see the Buddipole or similar setup as interesting.
