Helical Feed Antennas
- Helical antennas have long been popular in applications from VHF to
microwaves requiring circular polarization, since they have the unique
property of naturally providing circularly polarized radiation. Paul Wade W1GHZ

ICOM 746 Temperature Measurements
- The ICOM 746-Pro has acquired a history of NEC 1678G (IC-151) MMIC and driver transistor 2SK2975 failures. The failure of IC-151 appears to be a combination of ESD damage from electrostatic charge on the antenna entering IC-151, and perhaps thermal heat.
