yagi 2.4 ghz

Dismantable Yagi for the bands 10-17m - 10-12-15-17 meter band yagi antenna

Portable Magnetic Loop Antenna Version 2 - A simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres. For its size, the performance of the antenna always astounds me, although it is never going to replace a Yagi

2-Element-Yagis for HF  ^{updated  pop} - 2-Element parasitic Yagis for the Shortwave-Bands 10-12-15-17-20-30m. The antennas are feeded with the DK7ZB-match. A quarter-wave choke of coax is grounded at the socket.

3 Element Yagis Antennas for HF  ^pop - All these plans use the DK7ZB match

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

The DK7ZB-Match for Yagis - Simple, easy to built match developed in 1995 for Yagis with resistitive loads of 12.5, 18 and 28 Ohm.

Cross-Yagi - Cross-Yagis for Terrestrial and Satellite Work The 2x6-El.-Cross-Yagi (28 Ohm, 2.60m Boom) by Henk, PA3GUO

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.

Cross-Yagi antennas - For two purposes a Cross-Yagi can be useful Satellite work or if you need both vertical and horizontal polarization for terrestrial contacts
