Reviews Summary for Gees Antenna Farm 75 Meter Double Bazooka Dipole
Gees Antenna Farm 75 Meter Double Bazooka Dipole Reviews: 1 Average rating: 5.0/5 MSRP: $$49.99
Description: A double bazooka single band half wave dipole. The antenna is constructed with new RG6U and #14 solid wire. It has been set for 3.920. It can be operated across the entire 75 meter band without a tuner. Less than 1:5 SWR. The wire at the end insulators has not been soldered, so in the event you would like to move the absolute resonant frequency to your QSO frequency, you may do so by shortening the end to move up in frequency or add wire to the end to lower the resonant frequency. The antenna has 10/32 stainless steel bolts and nuts and ring terminals at the feed point. It is fed directly with 50 ohm coax (any length). Overall length is 123-ft. 6in. Also, these antennas are considerably quieter on receive. Comes with an instruction sheet.
Product is in production.

Excellent Single Full Band Antenna  Time owned: more than 12 months
I purchased a 75 meter (and a 40 meter) double bazooka from George, N5FIA in early 2003 (Gees Antenna Farm). Both George, N5FIA, and Dorothy, KD5EOF, are very nice to deal with.

A typical double bazooka is a broad-banded half-wave dipole, which exhibits very low standing waves across its intended band of frequencies. Also, it appears to be much quieter (not a lot but some) than my prior dipole and my current vertical (quite noticeable). This antenna exhibits very low swr across the entire 500 kHz segment of 75/80. In my installation it never exceeds 1.5:1. The design is typical of a double bazooka Ė a length of RG6U coax (75 ohm) that is connected to #14 jacketed copper solid wire on each end of the length of RG6U. The wire appears to be soldered very securely at the junction and wrapped very well with tape. The terminated ends of the #14 wire are twisted into a length of PVC (approximately 1 inch wide and about 5 inches long). The end attached to the PVC is laid bare for about 6 to 8 inches so if necessary wire can be added to shift the resonant frequency if desired. Also, one can strip some of the wire jacket and reduce the length by folding it over the end of the wire. Very flexible arrangement. At the center connection is an angled piece of PVC into which are attached two more straight pieces of PVC. On the center angled piece of PVC is a stainless steel eyehook. Two 10/32 stainless bolts, nuts and ring terminals are attached to the straighter PVC pieces. The ring terminals are for the attachment of your feedline. In my case of the feedline, itís about 75 feet of RG8X. The center PVC pieces are really wrapped tight and certainly appear to be thoroughly water proofed. This antenna has certainly not failed to perform since putting it on the air. Michigan weather has certainly tried with spring rains and wind, summer heat and thunderstorms, and fall and winter ice and snow. The maximum power I have put through it is about 600 watts. I believe itís up to stay.

As for performance, I occasionally get on 75/80 and donít lack for contacts. I did not buy this antenna as a super-duper end all DX antenna; I purchased this as a supplemental antenna to my vertical and for the fact that it covers the entire 75/80 meter band, so no tuner is needed for my vintage radios; coverage of North America is certainly achieved. Iím sure than given a decent property size and height of the antenna above ground this antenna would produce excellent reports and many contacts around the world. A short instruction sheet does come with the antenna. There is no construction other than the attachment method of your feedlineÖitís all completely constructed and tuned for a height of 45 feet above ground and the ends 12 feet above ground at a resonant frequency of 3.920. Comes well packaged with newspaper and plastic wrap.

This antenna is a single band antenna; should anyone expect it to be a multi-band dipole in any fashion, it is not. One can though receive signals on other frequencies than what it is designed for, but it is a single band antenna in all respects.

I also purchased a 40 meter double bazooka from Gees Antenna Farm and it also is built the same and performs excellently also. Highly recommend these antennas. More information on this antenna or the other antennas that Gees Antenna Farm has is found at: http://www.geesantennafarm.com
