I believe we found that wasn’t the case with the longer version?:
Honestly, don’t know what it is as the measurements don’t line up with 1/4 wave 1090Mhz, but it sure looked good on the meter.
Shots (a few posts back in same thread):
ADD/EDIT: Even more discouraging is the fact that the (short) PCB antenna that’s enclosed does NOT have the same PCB that they sell standalone. The standalone antenna (without the case) specs out much better and actually resonates at 1090Mhz whereas the enclosed (short) version is about 100Mhz off. At least mine was.
I have both short and long PCB antenna (enclosed), as well as the short PCB itself and all 3 are different in design. The short PCB is 170mm long, the PCB in the antenna with the radome (as depicted in this thread) is 130mm long. The long PCB antenna is 289mm long + 72mm wire. (PCB itself, not counting the radome(s)
