RF Antennas

RF Antenna Mk I

My first RF antenna was based on Peter Kerchoff's antenna design on his excellent PbP web pages. I used 4mm diameter aluminium rods for the parasitic elements and the reflector element, and a 4mm diameter brass rod for the driver element. The reason for using brass for the driver element, is that since this is the element that is soldered to the output lead, it would be easier to solder brass than aluminium.

My basic antenna cost was expensive - approximately 10.00, but this could have been reduced considerably if I hadn't have decided to use a carbon fibre rod.


RF Antenna Mk II

My second RF antenna is the one I currently use, and is a Sandpiper Aerials Yagi-Uda antenna designed for operation at 433 MHz.
