Any one have info on this Antenna Group. I have several new, still in the crate, AS-2687/SRA-17 antennas. These are 10' fiberglass whip antennas, capable of withstanding 160 MPH winds. Any info on how they were used on ships/ Subs or on shore? What Frequency range? Tx or Rx or both? Any info appreciated. Thanks & 73, John Allen W4GQT
