Well, I had set the program to optimize the antenna for 433Mhz as that is what I was going to start with on my tracking transmitter. Plugged the Yagi into my handheld, set the power to low, set the fwd indication on my SWR meter and then did the ref reading. I was shocked to see that it was 1:1.2. Set it up to 450Mhz and saw it was 1:1. For this new ham, it was pretty surprising for a first project. This is exactly why I never trusted gamma matches on 70 cm. I consistently got nearly perfectly flat matches all the way across the band using a gamma match. This usally something aint right. and the antenna is probably radiating more in the infra-red region than at the desire frequency. No doubt there are others more skilled than I who can make it work For me the quagi has worked to damned well for me to bother. Jimmie. |
