| 6 Element 144MHz to 175MHz Heavy Duty Log-Periodic antenna |
| Here is a very heavy duty log periodic beam antenna for the radio enthusiast. Although primarily designed as a receiving antenna, it can be used on transmit as well. |
Electrical Specifications:
6 Element Beam covering 144 MHz to 175 MHz
8DBi gain across the entire VHF High band.
Antenna Input Impedance 50-75 Ohms
Front to Back Ratio 25 to 30 DB across the band.
These values were verified using both computer aided modeling and real world measurements made at my
lab.
SWR, is 1.5 to 1 across 144 MHz to 175 MHz
Physical Specifications:
Antenna Weight 3.5 Lbs
Wind survival 80 MPH ++
Boom Length is 3' 6"
Boom Material is 2 of 1" square .050" wall 6063 aluminum in parallel
Elements are made from solid .25" 6061-T6 high strength aluminum
Longest element 42"
Shortest Element 26."
Elements are bolted to the boom with stainless steel Nylock nuts to prevent them from ever loosening up.
Mounting bracket is fitted for a 1.5" diameter mast.
Stainless Saddle Clamps included
The antenna can also be flush mounted using the mounting flange.

Paul,
My first impression of the antenna was how well it was constructed. Due to the inexpensive price, I was skeptical about the quality I would receive.
I was pleasantly surprised. The antenna was very easy to assemble, it took about 15 minutes.
We are using the antenna to receive NOAA weather radio for our TV station. We have a digital sub-channel that displays our weather radar 24/7 with NOAA audio.
We were using a quarter wave whip antenna on the receiver, and weren’t happy with the reliability. With the beam antenna installed, we now have a -63dBm received signal level. The NOAA
audio is now very clean.
Thanks for a great antenna.
