6 Elements, 70 – 70.5 MHz – 4m Yagi antenna PA70-6-4B

Low Noise High Gain PA70-6-4BG will make sure you can hear weak signals and give you the extra edge you need in contests or just enjoying the Ham Radio Hobby. 6 Element 70 MHz Yagi provides stunning performance across the band: 70 – 70.5 MHz.

The antenna has been calculated with the latest full 3D Electromagnetic Simulation Software, including the influence of the boom, brackets, and connectors.

Performances of such way designed antennae are extraordinarily better than antennas “designed” with just wire programs like EZNEC Pro/4 – NEC v5.0, 4NEC2, MMANA, AO, or YO that can’t calculate the influence of any metallic structure near the antenna elements.

That will lead to wrong predicted antenna performance like gain (about -0.2 to -0.5 dB), SWR (when tuned often very sharp resonance), and especially F/B (up to -20 dB worse than predicted) and accordingly absolute wrong G/T. Much worse than predicted. Just excellent on paper or web pages but not in reality.

Calculating with full 3D EM Software allows uncompromised performance. Much better than any other world competition. High gain, heavy suppression of all side lobes. Solid construction that can withstand strong gusts of wind of more than 160 km/h!

Guy rope support is specially made for high winds, heavy rains, or strong Sun. Designed tapered elements reduce wind load, as well as vibrations in the wind.

Pre-tuned antenna:

Before dispatch, we assemble every antenna and test antenna characteristics. That means you can expect all the electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to move, cut, tune, or use rasp for any element to get perfect SWR on the intended frequency range. Everything is pre-tuned.

That lead also to another very important detail. When assembled and tested each antenna is complete with all washers, nuts, bolts guy rope supports, etc. When packing all parts are already on the antenna. Without the possibility to “forget” important parts to put in the box. So you will always receive the complete antenna that we tested just before dispatching.


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
PA70-6-4B: 850 W
PA70-6-4BP: 1500 W
PA70-6-4BE: 2500 W
PA70-6-4BEX: 7500 W

Antenna Power Rating does not affect the electrical or mechanical characteristics of the antenna. PA70-6-4B, PA70-6-4BP, PA70-6-4BE, and PA70-6-4BEX have the same characteristics, only difference is in antenna maximum input power.


Like all our antennas, this PA70-6-4B antenna is a full package. Everything is included in the antenna box. The antenna, the balun with the connector, and the bracket with the clamps. Designed to last.
