Doug,

Assuming that your "swamp" is generally in the clear of everything else, and given your soil conditions, ground mount that sucker & lay down a reasonable number of non-resonant radials. By the way, by "ground mount" I mean position the feed no more than six inches above the ground.

I experimented with an elevated HF6V a number of years ago. The antenna feed was 10 feet in the air & I used four resonant radials, per the Butternut design in the antenna's instructions. It's tuning and performance were appalling & definitely not worth the effort I put into it.

Unless you can "droop" the radials to provide a better 50 ohm match for an elevated vertical I can't see any reason to not ground mount it.

regards,

I'm cleaning up a Butternut HF6V with 17m & 12m add-ons that has been out of
service for about 10 years. I'm trying to decide how to mount it and what to
do for radials. The area that is will be mounted in is very moist year
round.

Any advice on whether it would be better to mount it a few feet above ground
or if there would be a significant improvement in mounting it about 15' up?

Would I be better off with resonant radials or random length radials (ie:
convenient length for terrain obstructions)? How many? (I'm not looking for
a near theoretically perfect system, just a good alternative, for the higher
bands, to my 500' Windom until I can get my towers up.)

Thanks,
