Jeff, You will have problems with attempting to shunt feed a 100 foot
grounded tower on 80 since it approaches a grounded half wave radiator
and just to long on 80. The solution for this is to make a decoupling
sleeve on the tower by elevating the 80 meter feed up the tower and
bring down

Bill,
The stations on the RBN are automatic, and work even when unattended.
They are not like the DX clusters which require a manual post. Call CQ
and see. :-)

Hi Mike,
Thanks. Yes..I thought everybody
Thanks, Andy
I understand your IP and trade-secret issues. That's an interesting
approach. I'll have to give it some thought, although I don't expect to be
building preamps anytime in the foreseeable future. Was just curious why so
many J-310/309. Now I understand.
Have a good afternoon!
73,
I've done exactly what Herb suggested: hung a sloper for 80M off the
side of my 160M shunt-fed tower. Neither antenna knows the other is there
and both work pretty well - meaning I'm satisfied with what I get out of
them.
Interesting. I have tried verticals, slopers, inverted V's and other
80
To use a preamplifier or not (in a signal estimation) it seems to me it is
equivalent as to speak: to use the antenna for RX or not, to use radio or to
listen shout by a throat from mountain...
I exaggerate. But our radio and its functions are created to help the operators.
I sometimes switch
