SKU: 0405 Category:

3 Elements, 70 – 70.5 MHz – 4-meter band Yagi antenna: PA70-3-1A

The best performance antenna in the class length of 1m. Direct 50 Ohm feed. Designed for portable use as well as a stationary antenna. All screws, nuts, and bolts are stainless steel. The antenna is pre-tuned, so no need to move, cut, or use a rasp file for any element to get perfect SWR on the intended frequency range. A short boom, wide-band 3-element antenna covers the entire band with SWR <1.2 from 70 MHz to 70.5 MHz.

Everything is included in the antenna box: Antenna, balun with connector and bracket. 70 MHz Ham Radio Yagi is perfect for field days since it’s very easy to assemble. 15 minutes is sufficient. All antenna parts are labeled, so it is extremely easy to assemble. Just put number to number.

Elements are tapered to reduce vibrations at high winds. Boom is just 1 meter long. Since this Ham Radio antenna has 3 elements it is very easy to set up. The antenna is very good for field day since it is lightweight or a permanent setup since the antenna is very sturdy. The starting element diameter is 12 mm, the middle part is 10mm, and 8mm ends. Tapered elements will reduce the wind load. This Ham Radio antenna has a wide azimuth radiation pattern. 70 MHz 3 element is good for vertical stacking in a permanent setup since this wide angle allows listening to Ham Radio stations without frequent rotator movement.


PA70-3-1A 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.


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
PA70-3-1A 850 W
PA70-3-1AP 1500 W
PA70-3-1AE 2500 W
PA70-3-1AEX 7500 W

Antenna Power Rating does not affect the electrical or mechanical characteristics of the antenna. PA70-3-1A, PA70-3-1AP, PA70-3-1AE, and PA70-3-1AEX have the same characteristics, only difference is in antenna maximum input power.

  1. Eden

    The antennas are up & working great. I decoded S50B many times yesterday on 8m but was not in the shack then. Have been working with guys in the US and also decoded EI4GEB.
    I hope to make some Qs on 4m when the band opens up.
