2m calculator

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

A 40m Vertical - This antenna is intended as a simple, inexpensive solution for the newcomer to experiment across the 40m band (7.0–7.2MHz) when only restricted space is available

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

Cubical Quad Antenna Calculator - The function of the calculator is to give all of the needed sizing to construct a good 5 element quad antenna for amateur radio use.

2m Quagi Antenna plan  ^updated - A design of a 2 m quagi antenna by TA2IB

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.

Wire-Beam - Wire beam antenna for the bands 6m, 10m, 12m, 15m, 17m and 20m
