Pedestrian/Portable.
Base loaded telescopic whip with BNC. Fixed coil for each band.
*Special Notes: Both AH14
antennas we tried were resonant at above 15MHz.This appears to be a design
or production problem. SWR was way over 3:1, so the counterpoise was lengthened
to about 20ft to resonate this antenna at 14.1MHz! We believe this antenna
has higher loss than is indicated by the measurement, due to the fact that
the longer counterpoise "unfairly" contributed a higher percentage of radiated
RF. |
