I had always assumed these were all the same size but the connection to my Avtex TV is very loose in the socket. TV has been back to Avtex who report that it’s all ok. So reverted to bag of aerial bits in garage. Most connections were loose in the socket, one was a bit tighter and two were too big! Can you get adapters to tighten the fit or do Avtex sell their own? Currently get round problem by wedging aerial between TV and wall to stop movement in socket. Thoughts appreciated.

More than toes wet now!
You could try squeezing it SLIGHTLY out of shape with a pair of pliers to make it a tighter fit.

There will be a difference in quality but I've never seen a difference in actual size.
Like satellite F plugs, they are a standard size.

Avtex have probably misunderstood the problem and checked the security of the coax socket to the PCB board but not the actual socket for damage.
It's possibly been stressed and the outer ring expanded by the coax pulling sideways on it.
It relies on friction between the inside of the outer ring and the outer part of the plug for security.
Ideally needs a 90° coax plug so the cable isn't straining.

Got the same issue..on an Avtex from new.
I would not advise trying to pinch it up a bit..the socket will come away from its mounting point unless you are both incredibly careful and lucky !

Squidge the male plug - if you bu773r it up it's dead easy just to stick a new one on.

A thin sliver of aluminium foil wrapped around the plug might do the trick.

I took the cowards way out.
A strong(ish) elastic and from the tv bracket keeps it in place

I sold televisions for over 30 years and have never seen a different size aerial socket.
Mind you, it's a few years since I retired but I don't think anything has changed.

A tight connection in the aieiel socket probably won't be needed. The current we're talking about is very small (pico amps? Or less? ) and the high frequency of the signal is such that it will travel between 2 close pieces of metal like it would a capacitor, which is a high pass filter (y)

So why design the plug and socket to be a reasonably tight fit.
any movement between the two will cause picture interference......try it and see.

I always use the screw on connectors that convert satellite type F connectors to coax. They are much better quality than normal coax connector.
