If for some strange reason you MUST have the CD powered up while
listening to radio, get a better aerial or re-locate the cables.

As mentioned in reply to SP, when listening to CD while recording radio. And
before anyone asks, it's so I can timeshift and listen with the option of
fast forwarding through all the inane presenters, ads, tracks I don't like
etc.

Guess it's time to install an external antenna - Any recommendations? 3
element from Antiference or Triax?

Most folks would recommend Antiference, but basically *anything* will
be a vast improvement. My kitchen system (also on a Denon TU-260L, as
it happens), has a coax lead going up some nine feet to a simple wire
dipole nailed to a ceiling beam in the hallway. Reception is
excellent, and no problems with interference from other bits of kit.

Well seeing the amount of money people spend on cables and
interconnects;-()

Still recommend a multi element aerial to protect against multipath
problems tho..

Yep but if your going to upgrade your aerial you might as well just do it
once since even the most expensive (not including those huge 8-9-10?
multi-element arrays) is not much more money.
I'm not saying you should go for the most expensive but basically you want
it fitted and forgotten.

If the idea is to rid the tuner of interference then moving the simple wire
dipole could be a solution, but simply moving the antenna in my experience
as high as possible within the confines of the house will not improve it's
performance by much unless it is already badly placed (weak signals, noise).
While it may give quite a respectable and acceptable performance for a
kitchen system that provides just casual listening I would urge for more
serious listening a multi-element array.

Not always a good idea. Too much signal can also cause problems. In
addition, a more directional aerial may increase the signal from the
transmitter it is directed towards, but is also likely to reduce the
signal for other (typically local) transmitters in different
directions. In my case, the aerial is directed to the main BBC
transmitter at the expense of local commercial radio, which I
generally do not listen to.

Yes, but attenuators are cheap.

Also, I have some CT100 left over from my TV antenna installation - is
this
suitable for use with FM antennas too?

CT100 is an excellent cable for SAT/TV/FM and is far better than the
"damp string" that is usually sold as low-loss aerial cable. If you're
looking for FM aerials via mail order www.cpc.co.uk or .com is one of
the better suppliers. They do a fairly good range.


Yes, I have an account with them - got my TV antennas, cable, diplexer etc.
from them - good people to deal with in my experience.



Good listening..

TIA.

Multi-element aerials are a bit counter-productive now we're past the
BBC-only days when all you had to do was aim it at Wrotham or Crystal
Palace! We pick up FM from more than one direction now.

I get excellent results from a simple vertical dipole. I've taped 5
feet of wire to a garden cane hanging from the highest point in my
loft. Split in the centre, and fed down a coax cable to the tuner.

In principle a vertical dipole will pick up more in the round as it were
but this depends on the mounting arrangements. However, the day of the
multi-element isn't past as its still good to have some discrimination
against multipath which can impair FM reception. As to the ILR locals
well would anyone here call the average commercial station output
hi-fi?...

Why is it that people on here will spend a fortune in speaker
interconnects where a bit of mains flex or bell wire will work, and yet
expect their tuner to work of any old bit of wire or damp string?...

.. As to the other idea of the local transmitters you
won't go far wrong in getting the best signal from the main BBC TX and
leave the others to their own devices.

Here here. You can get quite a good signal of the back of a good installed
aerial.

If its anything like audio quality you're after. Most everything else on
the FM band is compressed to and back....

Yea true but if you are located anywhere near the east cost a bit of DX'ing
in the summer works wonders. You can pick up all those lovely foreign
un-compressed stations.

Yes the polarity of the way they transmit was changed some years ago to help
car radio reception in built up areas. However this seems to have had the
counter productive effect of reducing the effective area the signal once
covered.
I prefered the old days when you could travel miles and still pick up a
signal.
