While working in the back yard this morning I wanted to take down a couple dead
trees. Things didn't work out the way I wanted. One of the trees fell on one of
the Beverages. This Beverage was put up after following Steve's Ve6wz
construction tips. I had a copy of Steve's pulley system. And it w
Exactly! Doing that creates impedance mismatches at each end.
Now, if your aim is to trip people or animals, slope it. ;-)

Sloping the ends of a beverage serves no useful purpose

Sloping the ends of a beverage serves no useful purpose. That's an old wives'
tale (or maybe I should say old Hammy Hambone's tale) started by W1WCR, I
believe. Whether the wire is horizon
This is great advice, Greg!

Carol,
What kind of transformer are you using? The best transformers are the binocular
core transformers that have separate primary and secondary isolated winding's.
Did you keep the coax shield disconnected from the ground rod? The secondary
should connect the beverage one one wire and ground
Glad to hear that you solved this. :-) If everything's working you'll
notice a BIG difference in hearing low-angle weak signals 800 miles away, *and
especially way beyond that distance!* It's all about improving your RX S/N
ratio.
If you don't, then where is your Beverage pointed, and what state a
Hello all and many thanks for your solutions to my beverage problem.
It turned out that I had a bad transformer and several bad F-fitting
connections. It was the first time I had ever used a tool for this
purpose. Noise is gone on the beverage and as expected signals on the
beverage are muc
I have found that a common source of noise on beverage systems is the need
to use the small F type connectors and the crappy F type coax that is often
on the jumpers as well as just converting it all to the final input to your
receiver.
Try the simplest but clean and checked coax directly from
Hi
RG59 is 75 ohm and RG58 is 50/52 ohm. I'm sure the noise is not coming
from this difference, but swr may be there..

Besides common-mode pickup, *also* consider whether your Beverage antenna
is pointing at a source of noise.

Hi Carol
The big issue with any RX antenna is common mode noise, the feed line can
interact with all other wires in your station, including AC wires 115Vac,
rotor cables etc.

What value termination resistor, how far did you drive the ground rods, did you
slope the last 50' on each end?

Hello all,
I finally put up a beverage antenna...about 400 feet long. I am feeding
it through a 9:1 transformer with some 50 ohm cable ( RG 59). I am
finding that it is noisier than my transmit antenna, contrary to what it
should be. The wire stays about 6-8feet above ground. ground rods at
A neat and cheap insulator for along a Beverage is the C shaped screw in
insulator for electric horse fences. The ends of the C overlap so a
half twist allows the wire to be inserted and then held with 90 degree
rotation. It is then free to slide in the insulator. Most any horse/ag
