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

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.

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.

Mounting elements to a boom - Here is an easy method to mount elements to a boom, this can be realized at home, without the need of special tools

Use of tripods to assemble and balance big antennas - Here is a way to ease assembly and balancing of a large antenna. The elements and boom are assembled separately in most cases. Once they are all together set up 2 tripods in the assembly area and put the boom on them.

Elevated Magnetic Loop for 160 & 75 Meters Priority listing - Tree hung rotatable 160m magnetic loop antenna

2-Element-DK7ZB-Quad for 5 Bands - 10-12-15-17-20m A description was in the German Ham-Magazine "Funkamateur" in Issue 11/2003

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
