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 RG6 and surplus RG58/59 it is easier and potentially
cheaper than open wire feedline. Three transformers and no relays.
(page 7-88 5th edition and earlier editions as well)
Is there some reason that a pair of open wires are significantly better? Grant KZ1W On 11/9/2012 4:24 PM, Mike Waters wrote: 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 wire Beverage in the opposite direction, then you have to put up twice as many supports (unless you have trees). But with a two-wire Beverage, you can use the same supports for both directions. 73, Mike http://www.w0btu.com/Beverage_antennas.html On Fri, Nov 9, 2012 at 3:00 PM, Buck wh7dx <wh7dx@hawaii.rr.com> wrote:Use RG-6 line in the future and run another Beverage in the opposite direction - NW._______________________________________________ Topband reflector - topband@contesting.com _______________________________________________ Topband reflector - topband@contesting.com |
