5 Elements, 70 – 70.5 MHz – 4m Yagi antenna PA70-5-3B

5 Elements on a 4-meter band antenna can be assembled/disassembled pretty fast for portable use. The antenna boom is tapered with tick 30 x 30 mm aluminum. 5 Element 50 MHz antenna uses an extremely strong bracket with M8 stainless steel clumps, hence its well suited for permanent use too. Our 70 MHz antennas have tapered elements to reduce vibrations at high winds, as well as reduce wind load. Survival wind speed is 160 km/h.

All antennas are assembled and tested before shipping. There is no exception. All our Ham Radio antennas are pre-tuned. Once the antenna is up in the air, you should expect extremely good SWR across the whole designed range, true gain, and F/B as given in the table. You have nothing to tune, nothing to measure. Just put number to number and enjoy the Ham Radio hobby.

Everything is included in the 5-element 70 MHz antenna box: Antenna, balun with connector and bracket. Yours is just to assemble and have fun! As all our antennas are, this Ham Radio antenna has been designed with professional full-3D EM modeling software. The antenna is calculated with the influence of boom, balun, connectors…

PA70-5-3B Antenna is the best performance antenna in class length of 3m.


Power options:

The antenna does not have a power limit, the only limitations are in the used balun and antenna connector. The default maximum power input is 850 W.

Antenna label and its Maximum Input Power
PA70-5-3B: 850 W
PA70-5-3BP: 1500 W
PA70-5-3BE: 2500 W
PA70-5-3BEX: 7500 W

Antenna Power Rating does not affect the electrical or mechanical characteristics of the antenna. PA70-5-3B, PA70-5-3BP, PA70-5-3BE, and PA70-5-3BEX have the same characteristics, only difference is in antenna maximum input power.
