1 - Are you using a short test jumper cable or adapter connector
between the test instrument and the end of the coax? Could the test
lead or connector be at fault?
Nothing seems to make a difference. 12" coax
to the antenna, 50' RG8, 100' RG8, 50' RG58.
2 - Is there any possibility of a STRONG signal coming back down the
cable to stuff up your test instrument readings? Do you live near a
source of RF, such as local broadcast radio?
I don't think so. I'm receiving (I'm transmitting!)
just fine. No local signals clobber me.
3 - Is there any possibility both feeder cables are defective?
Perhaps you are using coaxial cable not meant for this purpose? TV
coax, or LAN cable?
Nope. Several 50 ohm 8/58 coax. Some from cablexperts.com.
4 - Have you wiped out your neighbours TV viewing or something?
Checked the cables for sabotage (pins or nails)?
No, nothing like that.
5 - Have you climbed the mast and checked the antenna directly at the
feed point, without a feeder cable?
I can't climb this mast but if I bring it down to 10' and
get up there with a ladder, same results.
You have probably thought of all these, but I had to ask.
Feel free to ask, no matter how seemingly stupid
the Q might be.
