ANTHF - Icom AH-3, 14' mast, 9' radials, tripod: Hello all. I'm stepping away from HF ham radio for a while due to tons of other projects and a need for space. The tripod is about 12 feet tall. I welded it up out of bed frame steel. The mast and ground plane radials all come apart. strong aluminum tubing with stainless screws. I think I did it all in 1/2-13. I ran this with an IC-7300HF rig, had a blast. Tuned most anywhere I wanted it to. No issues. Pickup only please.; Listing #1768173 - Submitted on 05/16/26 by Callsign K5NJP - IP: c-73-72-4-149.hsd1.il.comcast.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
