Ground Plane for FA Antenna?

[abcd567]

Some two-and-half year old posts. My help.

@abcd567

After purchasing 2 pieces (one spare) of N-male to F-female adapter (Click Here) from a local electronics & hobby shop yesterday, removed Cantenna & screwed (FA antenna+N to F adapter) in its place. All other things (Coax, DVB-T, RPi, Software, Settings) remained unchanged. Performed a quick check. FA antenna acts as if no antenna is connected. I replaced the N to F connector by 2nd piece, no change. Either FA Antenna is defective, or N to F Connector is defective (unlikely as I have tried 2 pieces). I will try to test it again. Do Amazon have Replacement policy in case I find the antenna is defective? I will ask Amazon to replace it.

Double check that the N connectors are 50 Ohm and not 75 Ohm - The 75 Ohm version has a thinner pin and may not connect properly if you plug it into a 50 Ohms socket.

The top ones are 75 Ohm, the bottom 50.

OK, I made a temporary arrangement to test where the problem lies, and eliminated N-to-F adaptor by connecting RG6 cable directly to antenna without any connector.

Now graphs & VRS range plot show improvement, but still far less than Cantenna.

Not sure, but the improvement may very well be because RG6 coax length is now 1 meter / 3 feet instead of 4 meters / 12 feet, and the FA antenna is now closer to window, but about 6 feet / 2 meters lower than Cantenna.
