More testing on 3.4 GHz using a WA5VJB PCB antenna as a grid feed

Hayden,

There are few tests you can do.

(1) rotate the antenna in the horizontal and see what the beam width is

(2)  see if there are any lobes - these will be evident if the feed is not quite in the correct position

(3) move the LP in and out to try and minimise any lobes  -   anything better than  -20dB is good!

(4)  rotate the antenna in the vertical and check what the vertical beamwidth is.

(5) given the symmetry of the feed, there  is nothing you can do about any lobes in the vertical.

(6)  Check what the conduit is doing RF wise - it might be affecting the return loss on some bands.


Perhaps your VK7 friend can put a constant carrier up on FM at low power for you to work with.


Cheers
