Hi all..
Is there any details on the web about this type of helix, have never seen it with a ring reflector in books. I have seen a few different shapes of reflector cup, and cone which can give a good increase in gain, but also the extra gain is not wide bandwidth.. I run a 12 turn helix now John

I've been using a similar (home brew) helix (including ring reflector) on 70 cm since AO-40 days. It works very well (see my QRZ page). The one being discussed has an extra ring reflector. _______________________________________________ Sent via [email protected].
