440 yagi design

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.

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

W4JOH Cobra Antenna - The original Cobra antenna, is a multiband 160 or 80 to 10 meter, designed by W4JOH is built using standard insulated wire of about 14 gauge and fed with 450 ohm ladder line down to the shack into a tuner.

Quagi antenna for 144 Mhz - A modified W5UN Quagi design optimized for 144.050 Mhz

Receiving Antenna Design - Learn basic theory on antennas, and notes on homebrewing efficient shortwave antennas

KC1XX Contest Station - Amateur Radio Station owned by Matt Strelow. The station is designed for competition in the multi-operator multi-transmitter category of high-frequency DX contests. Running with 7 towers 6 rotators, 8 beverage listening antennas, and 4 spotting verticals

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
