4 meter 70 -70.5 MHz 4 elements Yagi antenna PA70-4-1.5B

Low Noise High Gain PA70-4-1.5 will Ham Radio Yagi provides stunning performance across the 4-meter band: 70 – 70.5 MHz. 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 that can’t calculate the influence of any metallic structure near the antenna elements.

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! All screws, nuts, and bolts are stainless steel.


PA70-4-1.5B is a 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.

Worldwide shipping.


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
PA70-4-1.5B: 850 W
PA70-4-1.5BP: 1500 W
PA70-4-1.5BE: 2500 W
PA70-4-1.5BEX: 7500 W

Antenna Power Rating does not affect the electrical or mechanical characteristics of the antenna. PA70-4-1.5B, PA70-4-1.5BP, PA70-4-1.5BE, and PA70-4-1.5BEX have the same characteristics, only difference is in antenna maximum input power.
