How to make an HB9CV
How to make an HB9CV two element antenna for VHF
(or at least, how G8TTI made one!)

The HB9CV is a well known two element antenna of a directional beam type with a forward gain of 4 to 5 dBd.
This one is for two metres but it can be scaled, from the dimensions in the diagram, for other bands I have also made them for four and six metres.
The gamma match and compensating capacitor.
Fed here at the reflector, this matched okay and was easy to use as I just used mine for DF work, the extended boom acting as a handle. The capacitor will need weather proofing if the antenna is to be mounted outside.
