Re: Topband: Beverage Antenna Tuning

I find that my 600 to 1000 ft terminated beverages are quite capable. Clearly, if someone doesn't the room, then other options need to be explored. But the front to back ratio and SNR of my 1000 ft beverage to Europe is nothing short of amazing when it comes to hearing. Even with 1.5kW on 80 and

Re: Topband: Beverage Antenna Tuning

Guys Some concepts really belong to the last century, a beverage antenna is very inefficient for moderns days. Ground wave noise is very high everywhere and it is vertical polarized, any vertical polarized RX antenna will hear man made noise very well. The only really way to increase signal

Good point Rick. But that zoomes-out the topic. What priorities does Ash' beverage need to cover, like: lowering local noise (groundwave) lowering incoming skywave noise; QRN and/or QRM the need to 'enable another layer of QSO contacts' etc. etc. Ash:  I am sure you have already read some

Thanks Mike, I already purchased a unidirectional match from Array Solutions so I'm going to go with that for now to the NE. My next beverage will be bidirectional to the NW and SE. That should do it. It makes sense. I picked up about 500ft of bailing wire at the local hardware store and

Bryan, Use RG-6 direct burial or equivalent for the beverage connection. No need to use LMR400. You should be able to find it relatively inexpensively. Make sure you have a matching transformer for the beverage impedance to 72 ohms for the RG-6. W8JI.com will give you just about all the

Have you ever thought of using a 2-wire bi-directional Beverage? They are not complex at all. It only takes one more wire, two more simple transformers, and one more run of coax. A remote relay and four extra parts even lets you use just one run of coax for both directions. If you run a single

I'm not sure why the bidirectional coaxial cable Beveridge doesn't get more discussion. It is described in ON4UN's book, and seemed to work fine when I built one at a prior QTH, although it does take two feedlines from what would logically be the closest end to the shack. Given the price of
