I decided to fit a new Log Periodic (My favourite aerial)
At the same time I fitted a Antiference 4 way mast amplifier so I can supply the signal to other rooms.
Testing just the Aerial on it's own I had excellent signal level/quality.
Then I connected up the 12v power supply inline, now Antiference have changed the design of their power supply, they used to come with a linear PSU (PF1)
they are now including a Switch Mode PSU (PS12F) which is a tiny little thing and also does not have the ability to wall mount.
As soon as I plugged this in, my signal was fluctuating, if I moved it I'd drop signal completely. If I turned on a HDMI device the signal would drop.
If I put this power supply anywhere near the TV it would cause interference.
I stripped it down and it's absolutely crap inside, cheap capacitors and no shielding what so ever! I was expecting to see a dry joint on the F connectors or something.
I went outside and removed the Antiference mast head amplifier, went back inside and looped the PSU through (with a modified tap to stop the DC voltage) and the picture was fine as it was with just the Aerial connected to the TV, then I plugged the PSU back in to the mains and the problem started again.
So just replaced it this morning with a Wolsey 4 Way Mast Amplifier which came with a Liner Power supply, signal is better than ever and no issues what so ever.
I used WF100 throughout and Cabelcon compression F's, was a frustrating process as I really did not want to do that cable run again!
Avoid this! I think they are supplying these now due to stupid energy efficiency ratings and all that EuP nonsense. Not like a Linear 100ma PSU costs anything to run!
