<DIV>Matthew,</DIV>
<DIV> </DIV>
<DIV>Are you referring to springs that mount above the base to which the coax
attaches, such as the Bushcomm bases and springs? The co-ax on my spring
base runs inside the spring and attaches at the top of the spring to a SO239
connector. Movement in my spring doesn’t change the antenna length whereas
the Bushcomm would if it wasn’t fitted with its internal strap.</DIV>

<DIV dir=ltr>The base should have a wire that electrically shorts the spring,
otherwise bad things happen to your tuning point as the antenna moves.

Traveller’s Net, and even travelling o’seas (VK7 & ZL) I found the centre
