Dear Dr. Freemo: The antenna looks pretty good on the Standing Wave Ratio (SWR), I have encountered the subtle changes in SWR readings when an antenna flexes in high winds. Have you ever encountered subtle changes in SWR readings during high winds?

@freepeoplesfreepress I have not seen changes in SWR during high winds when measuring it under these conditions or from the radio. I can pick it up, however, when i use my higher end equipment. Its very small though.
@kilroy_was_here coil based traps yea :) All on the roof on my philly home, so very small footprint.
Nice seeing somebody else from PA showing ham radio stuff on the net, most of the time it seems like it's just folks out west who are doing that. lol
@kilroy_was_here haha yea they have more space there.
But check out a APRS map sometime, you might be surprised how active the east coast is :)
None that I specifically noticed. I get s2.5 to s4 noise floor though and im sure at least some of that is from the house.
Keep in mind the roof top radials act as a sort of shielding from RFI for the active vertical, so they are particularly good for rooftops.
The first time i installed this a decade ago though when id transmit my neighboors backyard light would turn on... which kinda sucked considering iw as running an APRS beacon 10 minutes apart :)
Yea its just cause they put more power into the band.. SSB if you arent talking but are pushig the PTT nothing will come out the antenna... it only puts as much power in aws the volume it hears... If you make a very loud whistle into SSB it would be almost the same as CW (except not quite as clean a tone obviously)
