[UK-CONTEST] What type of antenna wire to use?

[Clive Whelan]

Hi Stewart

Firstly, use stranded PVC covered wire. In a doublet configuration, any 
( minimal) stretch is of no consequence, and it's much easier to handle. 
Unless you have a special 1500w permit ;-) , 450 ohm slotted ribbon will 
handle all the power you need, and doesn't suffer from the problems that 
the flimsy 300 ohm ( TV type) stuff does in heavy rain. Again it is so 
much easier to handle. One ( or more) of the London retailers sells a 
special centre piece ( it might be called Ladderloc??) which will 
complete the job nicely.
