antenna wall plate

I'm going to install a Diamond X-50 in my attic and I'm truing to decide the best way to run the cable. I'm going to use some RG-8mini, N Type connector at the Antenna end and then a BNC onto my Whistler TRX2.

I was hoping rather than having the cable hanging out of the wall I'd use a face plate, and then a fly lead to my Scanner. I've not been able to find a wall plate with a SO-239 or other similar connector and thought I'd ask here.

I ran some coax cable from my TV antenna through the walls a few years back, and I left a draw string in there so I could pull extra cables down. Other than replacing the face plate with a dual TV / F Type Socket, I'm not sure that would be a good idea.

Anyone got any experiance with using a F Type Socket/plug like this? or have any other ideas?

F connector plates are okay if you go for a reputable make like triax or kathrein.
I use webro wf100 coaxial, its 75 ohm. Pretty damn good for the cash.

One thing, most faceplates have f coupling mounted into them,you will struggle with any coaxial fitted to screw the plate back on as the couplings reach quite far back (about 17 mm with f plug attached to coax). To work within the limits of a standard household 25mm deep socket box and keep the coax nice and straight, you will need right angle f connector adapter like this.

makes life a lot easier.its worth buying good ones.


Decent F plugs for WF100 (aka CT100)

You can get F socket to n type plug and F socket to bnc plug connector adapters.

Personally I would not add connectors inline, unless I really needed to. The attenuation from each connector may be small, but they do add up, with one joint normally adding up to 3 separate connectors & even if you are using good quality connectors that is still 3 insertion losses to take into account.
I very much doubt if a dual TV / F socket face plate will be anything but low insertion loss. Although it should only add 2 connections. However one of those, the one onto the face plate will be hard to make a good one & will probably not be a proper soldered or good quality crimp joint.
