Does anyone use or is familiar with the Diamond D103 120/300Mhz 2.15/5.5dBi Air band Receiving Antenna? Not to be confused with Diamond's D-130 discone antenna, the D-103 is a vertical mobile antenna for the VHF commercial/civilian and military aircraft bands. They're pretty scarce as I've only been able to find one Ebay seller that has one, and they are located in Taipei Taiwan. It's also expensive priced at $92.95+ $14.99 shipping. Below is the best picture I could find. It's two pieces, there is a top element that inserts into the top of the loading coil on the left. It's about 51" tall. It has a PL-249 connector at the bottom. I'd be interested in any comments both pro and con. I'm surprised by the limited choices available for this type of antenna. I'm certain professionals as well as hobbyist would provide a good market for dual band aircraft antennas.
