[UK-CONTEST] Fibreglass Mast

[Nubsey G0VDZ]

Dave I allways use a putover pole. It cannot do that as each section is 
fitted over the other.
 But I guess you could try glue, but then again you will not be able to take 
it with you on a field day I bought a 10m  putover pole on ebay for about 20 
quid
