<b>Subject</b>: [Spam?] [450] antenna (or feedline) woes</span>
<div> </div>
<div dir="ltr">I noticed this morning when I returned the meter to its normal position on the output of the TE systems amp that I was only getting out about 150 watts. I didn't check the reverse power immediately but when I put a 25W slug in backwards at 100W forward it shot up like crazy. Connected the nanovna and sure enough the match is completely screwed (with the tower mount preamp off .. which also makes a difference!) Oddly enough I'm hearing fine as I was tracking Rich up Rt 8 with no issues, so I suspect it may be water intrusion. It doesn't change when i rotate/shake the antennas so I don't think it is on the antenna, but it could be the preamp or the connection at the preamp that is at issue, or the old hardline, or the connection between the hardline and the coax outside at ground level. I can check the ground level connectors when the weather is nicer but if it isn't that I'm out of luck until my foot is healed well enough to get back on the roof. Gonna have to hook the loops back up.</div>
