[TowerTalk] Centre Insulator

[Mike Harris]

G'day,

I wonder if anyone can point me in the direction of a supplier for fibre 
glass rod suitable for bridging the centre of a split driven element.  The 
element I am assembling is the heavy duty 20m unit from the ARRL antenna 
Handbook and it will need to be 7/8 inch diameter to fit within the 1 inch 
O.D. tube tripler.  I'm only looking for approximately 12 inches.  DX 
Engineering only list a component for 3/4 inch O.D. tube.

Regards,

Mike VP8NO
