2m beacon

2m VHF antennas with high gain - 2m SSB/CW-12.5 Ohm Yagis with extrem high gain and small bandwidth. These Yagis were constructed as ultra-light, portable Yagis with extrem high gain. They have small bandwidth and are working from 144,0-144,8MHz with good SWR.

The 2-Element-HB9CV-Beam  ^updated - The HB9CV-Beam is a 2-Element-Yagi with two driven elements and was introduced by Rudolf Baumgartner, HB9CV in the 1950ies. The Beam is a coax-feeded version of the ZL-Special Construction by DK7ZB for 2m, 6m and 10m

J-Pole antennas for 2m-40m - A multiband jpole antenna

Simple Dipole Antenna for 2m - A simple portable dipole antenna for 144MHz

DK7ZB 144 mhz Yagis - High gain, good pattern and acceptable bandwidth. These aims can be realized with a radiation-resistance of 25-35Ohms, because the 28-Ohm-feedpoint is very simple to match.
