May I suggest for a limited space antenna the MFJ-1786 loop. It
covers all freqs between 10 and 30 mhz and is 3 ft (36 inches or 1
meter) in diameter.|
I used one that I disguised as a T.V. antenna on my roof top in a HOA CC&R home and worked DXCC and all the contests. It out performed a R-7 that was later replaced by a R-7000 mounted on a 10 ft pole as recommend by Cushcraft.
I have attached a pic of the antenna to give you an idea of the installation. Those of you who are CC: should be able to see the pic although the list won't see it due to attachments being rejected.
I would also suggest the R-7 or R-7000 or their later versions over the 5BTV as they do not need the long radial wires at the base since they are 1/2 wave antennas vs 1/4 wave for the 5BTV.
My humble opinions only. Good luck.

Tom, Great stuff as always. Have a similar scenario about to happen here. Just moved to a smaller lot and for the next few years a tower is not part of the plan, so a vertical in the backyard (with many radials) will have to do.
