For VHF/UHF communications I use my trusty Yaesu FT-7800 rig, which I have mounted to the bench in the shack. Up on the roof I have a DX-60 vertical 2m/70cm antenna that is fed with a length of RG-213 coax. And it seems to work well.
I have just bought myself a nice little SWR/Power meter, a Nissei RS-40 with which I can see what is going on regarding my signals on UHF/VHF. Until now I have been operating ‘blind’.
I decided to measure the SWR on a few frequencies on both bands to get a better idea of how my antenna is doing. This is what I found:
Imagine then my surprise. Seems the dual bander is really a mono bander! From now on I will restrict my operations to 2m using this antenna and will put up a rotator and 2 element beam for 70cm, thanks to Wallace, VK4CBW who gave me the goods.
Watch this space.
