I use an inverted V for 75/80 meters. It hangs from my tower from about 80
feet and has worked fine using a tuner for the past 6 months. Last night
the VSWR went out of sight. After a while trying different tuner settings,
it was brought back to flat. However, as I began to transmit (SSB) the VSWR
went wild again and I had to settle on listening to the guys on the net.
What problem should I be looking for? The antenna is an Alpha-Delta DX-80.
I have had it for about 5 years in various operations, including the past
two Field Day operations. It is fed with about 90 feet of LMR-400 plus 50
feet of RG213 connected with a barrel connector. We have had a lot of
rainy, cold weather over the past two months and I am wondering if the
problem may be caused by resistivity in the wire connections at the center
insulator.
Thanks in advance for your response.
73, Keith NM5G
