Cheap Yagi Antennas for VHF/UHF

These antennas are relatively small, easily constructed from common materials/tools and have surprising performance.
The feed method is greatly simplified by directly soldering the coax to the driven element. No baluns or gamma matches
are used in this design. This simplified feed uses the structure of the antenna itself for impedance matching.



Coaxial Colinear

You can build a colinear from coax by following this design. You will need to scale it to suit the frequency you wish to use.



A Double Quad Antenna for 1296 MHz

This antenna is a medium gain directional antenna for mobile (portable) and base station use. I have built it many years ago for mobile operation to check out how good the signal of the
ATV Relais DB0SCS is received in the villages around Schwabach (the QTH of the Relais). I found a similar type for 432 MHz in the literature and decided to calculate the dimensions for 1296 MHz. For the 432 MHz antenna a gain of more then 10dBd was mentioned. This seems reasonable for the size of the antenna. I was always satisfied with the antenna and a direct comparison to other antennas of a know gain showed that it really has to a have a gain of about 10dB over a dipole.
