[TowerTalk] Slinky-type antennas

[kd4e]

Check the metal used, it has in the past been very
inferior for RF purposes.

Wonder if copperweld could be more tightly coiled
than usual for an application like this?

Might have to be heated the first time?

>> Has anyone here played around with a di-pole using 2 slinkys (not real 
>> slinkys but looks like them)
>> With a metalic bar in the middle of the coils part way down its length and 
>> the rest of the length pvc.
>> You could use a pully system (motorised or by hand) to change its length.

>> Just brain storming.....
