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.
