Be interesting to know if the tuners in the other equipment show anything different. That might point to an overload. I doubt the performance is the same on all of them. As has been said, a loft aerial is going to attenuate higher channels more than lower ones of course so any interference might be worse. Brian There are multiple reflections in lofts, so it is much harder for an aerial to discriminate against unwanted signals. Polarisation discrimination also suffers. The aerial itself might be de-tuned by the close proximity of other objects, leading to degradation of the polar response. Bill |

Could this be 4G signal interference? I've been looking for a filter that
still allows CH60 to be received but so far no luck. Thanks everyone. I've emailed at800.tv to see if they can send out a CH60 4G filter. That should either fix it or prove the problem is something else. -- WCZ |

When the changes were made for 4G those responsible issued a promise that anyone affected could have such a filter from them, for free. In reality, of course, some who were affected didn't know the cause, or about the above promise. So phoned their local TV bods who then probably charged them for remedial work. ...and they duly didn't appear in the statistics of how many people were adversely affected.

FWIW The filter they sent me is distinctly longer, physically, than the ones I tested from other sources. But I've not opened any of them to see if that is simply filled with added air. :-) Seemed to do the trick here though (with one mux on Ch60-) Jim -- Please use the address on the audiomisc page if you wish to email me.

Yes, it might be 4G if a new base station near your line of sight to the Oxford TX has started up - or a close neighbour is now using 4G. You *might* find adding an attenuator reduces the problem if you can't find a suitable filter. There was a body that promised to send out free suitable filters to all who needed them.[1] [1] I've forgotten their name but someone else here will probably recall it or know if they can still send out filters. Did you mean these people? https://at800.tv/ James |
