2 Elements, 70 – 70.5 MHz – 4 meter Yagi antenna PA70-2-08A

70 MHz small Yagi antenna PA70-2-1A. It is 2 2-element Yagi designed for a 4-meter band. In the box is everything included. Antenna + balun with connector + bracket… Elements are tapered to reduce vibrations at the high winds. Boom is just 0.8 meters long. Since this Ham Radio antenna has 2 elements it is very easy to set up. The antenna is very good for field days since it is lightweight or even for 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 the widest possible azimuth radiation pattern. 70 MHz 2-element Yagi is good for vertical stacking in a permanent setup since this wide angle allows listening to ham radio stations without frequent rotator movement. It is good for E-sporadic season since when there is an opening you don’t need much gain for it.

This 70 MHz has the best performance in the class length of 0.8m. Direct 50 Ohm feed. Our antennas are constructed with the best quality materials for the best mechanical properties and longevity. All screws, nuts, and bolts are stainless steel.

Due to the 4m band being fairly low in activity, we want to support and offer special low-priced antennas.

Power options:

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

Antenna label and Maximum Input Power
PA70-2-08A: 850 W
PA70-2-08AP: 1500 W
PA70-2-08AE: 2500 W
PA70-2-08AEX: 7500 W

Antenna Power Rating does not affect the electrical or mechanical characteristics of the antenna. PA70-2-08A, PA70-2-08AP, PA70-2-08AE, and PA70-2-08AEX have the same characteristics, only difference is in antenna maximum input power.

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.

 

Measuring the SWR of the PA70-2-0.8A antenna.

Measuring the whole band from 70 MHz to 70.5 MHz. Measured with HP8753ES 6GHz Network Analyzer. SWR is less than 1.1 across the designed range.
