> I finished the installation of the first two 'two-wire' Beverage antennas
a

560
> feet in length. The NE/SW Beverage will be 1360 feet long and the NW/SE
one
> will be 1100 feet long. All are 'cone-of-silence' lengths. Being able to

> With the first two installed, I was able to compare them with the pennant
> and evaluate the pre-amps with the antennas.

> I wish to extend my extreme thanks to those who sent me their pre-amps for
> this evaluation. The only one I did not have to compare was the Elbert

units.

applications.

> A word of caution is in order. The feed-point for all of my Beverage
> antennas is with 50 feet of my 160M vertical. One antenna passes within
ten
> feet of the vertical. With 1KW to the vertical, I wound up blowing the
> 2-watt 51-ohm resistors in the control box that switches the receiving
> direction. No, I didn't blow any pre-amps because I didn't have them in
the
> line. That is one reason my preference was for an indoor pre-amp.

> The preamps from ICE are available as single-band units.
