Hi
I have had to move my chimney to the . I now struggle to get BBC 1 or BBC 2 although ITV and and 5 are fine.
Should I change by 18 element long bar aerial to a log periodic with a head ?
I am about 16 miles of the .

Thank you.

Why did you have to move the from the outside of the to the inside ()?

Outside aerials generally receive better strength than those in the loft because of the bricks, mortar, tiles, etc being 'in the way' of the signals. Did you have it properly aligned to point at the ? I ask because a friend live just off Russel Road and have excellent on a log periodic on the roof wiothout any need for an .

I would suggest having the alignment checked or perhaps replacing the current aerial with a log-periodic (to suit future allocations) mounted outside for preference. Be careful about amplifiers as too much signal strength often gives worse results as it's 'too much of a good thing' as is more important than strength. Similarly, too little can cause problems too! For most TV sets a strength displayed as between 50 and 80 % is adequate, more than that is usually too much! Less than that is often too little.

Hi, still having problems in despite retuning daily. Switches between high and none repeatedly across all or just some. Any ideas why? Never had any issue before.

Brian Gregory: Yes, it seems they have. I'm presuming that you use the to receive ? If so, then you are correct to think that the ERP has been increased for the new com 7 . All the other multiplexes are either 25KW or 50KW. The come 7 multiplex on launch was 29.5kw, and it has now been increased to 36.7kw.

I am in an area of relatively good for the (NW8 post code but signal obstructed by tall blocks) but we have a good mounted on a very tall pole and have had never had any problems with the TV signal.

Just recently we are getting a significantly degraded signal on the ArqA Ch 22 signals, such that we either have horizontal lines, blocks, or even . Reception of all other is completely unaffected.

Since re-tuning on the 3rd of September as requested by service pop-ups I can no longer obtain Channe 5 in Enfield, North . I have tried a factory reset and several re-scans all to no avail although oddly the Chanel 5 + 1 is available.
