From 'Foundations of Wireless', M G Scroggie, 1958. Radiation and Aerials BRIDGING SPACE IN THE FIRST CHAPTER of this book the processes of radio com- munication were very briefly traced from start to finish; since then we have considered the sender in some detail. Before going on to the receiver we should know something about how the space in between is bridged. We have just seen how electrical...

Just got a new PC and it gets Freeview but I'm wondering how computers go on with HD programs. Will there be an update to do it ? Regards David

Some time ago when I used a lot of Antiference products I got really cheesed off with the oversized dipole assembly, the missing items, and the support arm that didn't fit between the elements of a Gp B aerial, so I spoke to the firm about these issues several times. Their response was such that I now use Blake aerials. Just now I typed 'Antiference' and the spellchecker suggested...

Hi, please could one of you kind persons help me with some info on the installation of a tv aerial using a swires terry meter. I should be recieving the meter in the morning and hopfully installing the aerial on Sunday morning. The location is M26 2QQ (Radcliffe Manchester) and i think the transmitter i should be aiming for is Winter Hill, but when it come to using the meter i am at a total...

I'm pointing to the Nottingham transmitter, about 8 miles away and looking at all the new aerials going up mine looks very sad, see https://picasaweb.google.com/lh/photo/zOQ3FzTCNlWCiIVk_6L04cMxbFCeIbubrXUGnJNUOQ4?feat=directlink I get analogue ok, and acquired a digibox a couple of years ago. Originally I could get very little, but bit by bit I'm getting more and more. Last year for instance...

Just as the 5pm news was starting on CH5 it went blue screen then "no signal" caption, pressing the channel change button a few times - all channels the same. Set it to rescan and switched to (grainy) CH5 analogue till the rescan was done - everythings back now. What happened?

Well BBC2 has gone - but all of a sudden CH5 is almost watchable. Wrong aerial group apparently, experiments with aerial boosters came to nowt.

Popped into a trade aerial & satellite place this morning to grab a few bits I needed on the fly. Stock checking at home has gone a bit awry and I had run out of some essential items! Had an interesting question and answer session with the owner. ME Hi. Can I have some double lashing chimney brackets - galvanised please? SHOP Sorry but we don't stock them anymore. ME ...

I'm trying to evaluate DSO options for the multiple blocks of low rise flats where I live. Sky seem to operate a don't let the punter read anything useful/negative, just get them on the phone to the salesman, sort of of web site. The idea of free installation is certain to be raised, although I don't think they will get their four subscriptions per block, and what is on the web site suggest...

The mast is 20 miles away, line of sight, good solid one required as lots of crows and fat pigeons perch on existing aerial. Don

My Humax 9300 EPG is showing all programmes for the entire week following 1am Saturday as starting one hour before they actually do. Anyone else have this? -- John Dean Oxford

There is an additional issue that currently the Dover transmitter is about to have its existing UHF aerial cylinder yanked off by a helicopter, and its new post DSO array installed. Supposed to have happened (might have already ?) on Monday, but all services will...

As soon as DSO is complete everyone who can get BBC1 will be able to get BBC News. If we lived in a logical world, therefore, there would be no need to interrupt BBC-1's flow of trivia and light entertainment with a news bulletin. All that would be needed would be a mention at the 6pm programme junction of the BBC News channel. Then BBC-1 would be free to show Tom and Jerry or something...

A friend has moved to a house in a town 75 miles from here. She rung to ask me if I thought the price she had been quoted for a 'digital aerial' was 'reasonable'. The price was £600 + VAT for an aerial, masthead amp, and two feeds. It is, allegedly, a very bad reception area, yet everything I can find out from here suggests that it isn't. Somewhat staggered I have had to say I'll go up and...

I might have been in the background on Friday on the Interview with Claire Bloom but I can't get the program on iplayer, have been looking on the Look North web site. Does Look North not appear, the crew told me it would be on iplayer from midnight that night. Regards David

Do Sutton Coldfield transmitter vary the output on HD trx or did I catch it under high pressure lift conditions? Went and bought a margin riser amp for the DAT45 to celebrate,.heh heh, but it seems weaker..the Humax HD Fox t2 amp 5v supply don`t hack it so I had to use my old Antiference 1240 psu...might put the original driver element back in the DAT45 :( ... unless some kind gent can tell me...
