Ceramic Patch Antenna encased in
EPOXY radome with MAR-6 amplifier
and magnetic mount.
GPS Antennas
Helical antennas from a design by Tom Clarke W3IWI.
The design uses 60mm waste water pipe, with 2 turns of wire [ The alternate
design uses window tape]. 1/4 turn if the wire at the base is paralell
to the base. The signal is amplified with a MAR-6 MMIC.
The picture on the left is a MICROWAVE DISH. On the
right is a microwave antenna. It comes from an ARRL design in 1995, using
PCB rather than steel. It is made from 2 pieces of PCB, some 5mm spaces
and an MAR-6 MMIC.
