Antennas Amplifiers PA144 Monoband Yagis for 2m

Technical description

The popular YU1CF / Antennas Amplifiers 2 meter, 144 MHz Yagi antennas offer a good gain related to the antenna length. Side lobes are excellently suppressed. The development was done with "Full-3D EM" modeling software.

These antennas are characterized by their low noise design, suitability for wideband operation and are equally suitable for EME, terrestrial or FM repeater operation. They have excellent mechanical properties to withstand all wind and weather conditions.

Mast mounts and balun with "N" connector are included with all antennas. There are no "hidden costs", everything needed is already included.

Application description

A total of 15 variants of the 144 MHz Yagi are available. From operation to local repeater to demanding EME application - just choose the antenna that suits you.

7 meter long, guyed 12-element yagi, ideal for EME and Tropo. Load capacity 1500 watts. 

PA144-13-8BGP

This very low noise 13-element Yagi offers excellent gain values, maximum power handling is 1500 watts. The boom is of course braced. However, with a length of 7.84 meters, it no longer fits on the roofs of many row houses.

PA144-14-9BGP

This world champion antenna ("2 meter world best G/T Yagi on 9 meters boom antenna", manufacturer's specification) with 14 elements has a proud boom length of 8.85 meters and a power handling of 1500 watts. The gain is a sensational 16.9 dBi (in free space).

PA144-16-12DGP

The largest antenna in the series is this 16-element high-performance Yagi. It is a stately 11.3 meters long and with a gain in free space of 17.5 dBi does not need to hide behind even longer antennas.
