New, inexpensive 1090MHz antenna for sale

The FA Antenna+FA Filter+ProStic is the best option I have used up to now.

I have 2 setups. My stats show the FA combo gives much better performance: Message rate 182%, Plane count 114%

Pi-1: Cantenna + 12 ft RG6 Coax + 12 inch RG316 pigtail + Black DVB-T (No Amplifier) >> plugged directly into OPi PC
Pi-2: FA Antenna + 4 ft RG6 Coax + 4 inch RG316 pigtail + FA Filter + ProStick >> plugged directly into RPi Model2

Note:
(1) Both antennas are at same location in same vertical line. Horizontal distance = 0, Vertical distance = 1 m / 3 ft
(2) There is NO AMPLIFIER with Cantenna + Generic DVB-T, while ProStick has a built-in RF amplifier.
