I hope if I am able to get as far as the
building process it won't take me much more than that. It would
be nice to have my own machine shop for some things. My
equipment amounts to a cheap drill press and my workbench is the
garage floor hahaha.

Use straightened coat hangers, I'd bet you would find it very difficult to prove a "proper" antenna was better. 73 Alan G4ZFQSince you are NOT transmitting, SWR really doesn't matter all that much. Why not use the tried and true method of a dipole cut for 54.310Mhz and the reflector 5% longer and director 5% shorter. The spacing set to .125 the wavelength on the director/reflector distance to driven element.Coincidentally I recently built this quick and dirty 8 element Yagi for 434 MHz. I used pieces of 14 gauge wire for the elements, coat hangers would have been better :) https://www.hfunderground.com/board/index.php/topic,69753.0.html Chris Smolinski Black Cat Systems Westminster, MD USA https://www.blackcatsystems.com |
