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

5 Elements on 4 meter band antenna can be assembled/disassembled pretty fast in portable use. Antenna boom is tapered with tick 30 x 30 mm aluminum. 5 Element 50 MHz antenna uses 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 the high winds, as well as reduced 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 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 modelling 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:

Antenna does not have power limit, only limitations are in used balun and antenna connector. Default maximum power input is 850 W.

 

Antenna label 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 electrical or mechanical characteristics of the antenna. PA70-5-3B, PA70-5-3BP, PA70-5-3BE, PA70-5-3BEX have the same characteristics, only difference is in antenna maximum input power.
