<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.

day I’ll actually get to ‘play radios’ again and be able to join you on air;
but in the meantime have to console myself with reading the mail and storing
up the good ideas; however in earlier times as Net control for the 14.116
Traveller’s Net, and even travelling o’seas (VK7 & ZL) I found the centre
loaded Hustler system to work well on my 80 Series (bull bar) and
borrowed/hire cars (tow bar). Simple, convenient, effective – and no I don’t
own any shares.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE:11pt;FONT-FAMILY:"Calibri",sans-serif;COLOR:#1f497d">Main
components are HD spring loaded base, a common folding articulated ‘mast’
section (1/4 wave on 6m) onto which fits coil loaded ‘resonator’ for
whichever band – available for 80m – 10m including
WARC.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="FONT-SIZE:11pt;FONT-FAMILY:"Calibri",sans-serif;COLOR:#1f497d">My
subjective observations were that it out performed the Codan 9350+ 1.8m SS
whip on any given band. <u></u><u></u></span></p>

presume they are still available – have not had to look as I have several sets
including the suitcase-ready one. Just don’t try taking it onto a cruise liner
or they will lock it in the hold!!! Rotten spoil
sports!<u></u><u></u></span></p>
