Extension cable for FA stick


Hi all, I’m looking to get my screw in antenna up in the loft for even better coverage it’s not possible to get the PI up as the power socket isn’t very good

I’m not keen on a USB extension as that would require a huge hole drilling to get it through

Browsing through Amazon I’ve found this https://www.amazon.co.uk/gp/product/B01FW1FZ7E/ref=ox_sc_act_title_1?smid=A3EDVZIJLWZ11I&psc=1 would that be suitable?

If not any suggestions from UK suppliers?


It says WiFi in the description, which set alarm bells ringing, but it seems not to be the reverse polarity version of sma, sma-rp.

Many people seem to use quality “normal” coax cables, RG6?

What is wrong with the wall socket. The pi does not need that much power…


It blows the fuse to get it sorted wouldn’t be easy so I need an extension cable of some sort


Reading the comments this seems to work with ADS-B antenna


Personally i would just get an 230V extension lead, snip the plug off and feed it through the hole. Then install a new plug (available from whereever)

Anyway i’m running a short length of cable so i can’t really tell if it’s good on longer runs.
But it definitely seems quality and the values look good on paper:

Good luck with your installation.


RG58 is fine at lower frquencies, but is not low loss at 1090MHz. If you are buying 50Ohm coax for ADS-B, go for LL195, LMR200 or similar.

I’d think that needs fixing as a priority (or leave the fuse out).

If you can get UTP into the roof space, PoE works well.


Another vote for power over Ethernet. I had MLAT timing issues with a USB extension cable after a few months.

I used these adaptors with a redundant 20v laptop PSU to power the Pi over network cable into loft.


I use this configuration.
