Broadband Passive Blade Antenna - 12-124

The 12-124 is a broadband passive blade antenna dedicated to the frequency bands 108-156MHz and 225-400MHz. The antenna is configured as a broadband fan. The radiating element is fed via a tuned circuit to enhance gain at 108MHz and a frequency-dependent resistive pad network to provide acceptable match at lower frequencies.
