antenna

Hi, I got the planefinder rig, with the Active Antenna mounted on a metal tube on the roof, I have a pretty good coverage, but I wanted to ask if raising the antenna would give even better. Thanks!

Has anyone used this amplifier with adjustable gain with their ADS-B setup? Did it improve your overall coverage? Here is the link to the amplifier on Amazon: https://www.amazon.com/gp/product/B084YQX5Q6/ref=ewc_pr_img_1?smid=A3LYGL3VCPC7H8&psc=1

Simulation results show that CoCo is a High Gain, High Impedance/High SWR Antenna. Due to its high SWR, an impedance matching device is required to be incorporated in the feed coax (i.e. between CoCo and Receiver) to bring down SWR to 1.5 or less, in order to fully utilize the high gain of CoCo...

SIMULATION RESULTS Gain = 3.7 dBi SWR = 3.1 Impedance = 155 - j 8.18 ohms HIGH IMPEDANCE/SWR - WILL NOT GIVE GOOD RESULTS WITHOUT IMPEDANCE MATCHING IMPEDANCE MATCHING BY "TRANSMISSION LINE+CAPACITOR" TECHNIQUE Using Smith Chart: Capacitor to be inserted = 3.8 pF (4 pF will do) Coax length...
