Elevated radials?

Asunto: Re: [TowerTalk] 80 meter antenna choice

Given those constraints, I would take a 4SQ over whatever ground I could
manage vs. about anything else mentioned.

This one has a driveway in the way.  Most of the decent sized radials would be pointing away from the direction the NE and NW are facing and the others would be fairly short.

I've used this system in the past and it performed quite well.  I'm concerned the lack of similar radial systems would ruin the F/B and gain and the compromised radial system of two of the antennas would also be an issue.
