HGP-500

Marconi,
I built the antenna per the instruction manual which called for 8'9" per radial the only change I made that was different was the overall height was listed at
19' that would be for 10 meters of course. I set it to 22' then I dropped it to where the SWR using my MFJ-259A was close to 50 ohms at CH20 27.205 1.3 SWR and CH 1 & 40 were 1.5. Think the overall height ended up around 21' 6 or so. The 8'9" radials butt up against each other the way the radial plate is. Happy with the antennas performance. Am using 100' on RG213U to feed this antenna at 30' TTB. Hope this is of some value to ya. The antenna WORKS an the receive SOUNDS RIGHT to my ear........Oldtimer
