I need to get a FM ariel but it need to go in the loft space not the roof. Any good ones

I advise you contact the BBC re your local TX. No point spending £100 if the local TX is 15 miles away and clear line of sight to it. If OTOH you are in a valley miles away, behind a steel frame building, you need a big twig.;)

You can find your nearest FM transmitter online..:

I recently installed my Galaxie 17 but found the bbc info next to useless.

This link http://fmscan.org/index.php will allow you to set up your location and then gives you the calculated signal strength for the fm xmitters and most importantly the compass bearing.

With a loft installation there may be practicalities on which directions the aerial can be pointed.

I used a bog standard 5 element Antiference aerial in my loft in the last house. Cheap from places like Maplins. The more elements the more directional will be the aerial and this is good if you have interferance from strong off-beam local sources.

If you are next to the Xmiter than a simple dipole will suffice.

Lastly check the sensitivity of your tuner and see if you have enough dB μV else you'll need a high-gain (ie more elements) aerial.

wow what agreat web site - cheers
just need to undestand it :)

well it looks like a stronger signal from the mast up on dartmoor 35km away rather than one which is only 11km away ?
anyhow 69dbum seems good, even if you take in 10 db losses still gives around 60dbum's

Well 60db μV = 1mV So as long as your tuner is more sensitive ie less than 1000μV than you'll be ok.

Yes I am pointing at the main high-power Xmitter 58Km away as I get (theoretically) 65 db μV (almost 2.5mV) as its output is 250KW whereas the local repeater 15Km away gives 59 db μV (less than 1mV) as its output is a meer 100W!

The only other point to consider is off beam interference. So measure up and get the highest gain antenna that'll fit.

Cheers Darth, and may the force be with you, dark side of course :)
