Topband: Beverage construction

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

Re: Topband: Beverage construction

Exactly! Doing that creates impedance mismatches at each end. Now, if your aim is to trip people or animals, slope it. ;-) 73, Mike www.w0btu.com On Nov 27, 2017 4:55 PM, "Donald Chester" wrote: > did you slope the last 50' on each end? Sloping the ends of a beverage

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

Re: Topband: Beverage construction problem solved

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

Re: Topband: Beverage construction problem solved

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

Re: Topband: Beverage construction

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

Re: Topband: Beverage construction

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.. Pedro - CT1EKD Citando Carol Richards : Hello all, I finally put up a beverage antenna...about 400 feet long. I am feeding it through a 9:1

Topband: Beverage construction

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

Hello I was Reading http://www.w8ji.com/beverages.htm to refresh me about beverages. I am installing a temporary beverage for next weekend. I will use bare copper wire, because will be light that the one that have a plastic cover (liner?) But now I am thinking about the antenna and

Re: Topband: beverage construction

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 supply
