7170181
Cardioid array 177-186 MHz
Description
- A linear array of two VHF dipole elements with phasing harness mounted on an aluminium boom. Careful attention to element phasing results in a “Cardiod” shaped radiation pattern with high F/B ratio compared to an equivalent sized Yagi antenna. Antennas of this type find use in PMR/Trunked Radio and Broadcast applications needing very high F/B performance. Produced to the highest quality standards, these robust antenna designs will insure reliable operation in harsh environmental conditions.
- • Former Jaybeam brand product.
