Well Adam I found a 10' length of coax and did as Geoff suggested and just pushed the centre wire into the socket and it works
It will be even better with the aerial that Gary is sending, so very nice of him
I am amazed by the sound of this little tuner even with my bit of coax... It is definitely the cheapest bit of hifi I have ever purchased in more than 30 years but it really is good.. Classic FM playing at the moment
Thank you to all that recommended the Denon
