I am wondering if anyone knows anything about using Radio
Shlack's telescopic, center-loaded whip antenna (catalogue
number 20-006) with the HTX-202 portable 2M rig. According to
the HTX-202 manual, the portable rig should be usable with this
So I bought one, thinking that it might be a better antenna for
hand-held portable use, than the "*** duckie" that comes with
The instructions that came with the antenna indicate that it
should be adjusted to a certain length according to a formula
(I forget the exact formula quoted in the instructions; but it
was something like antenna-length(inches) = 28?? / freq(MHz),
but I forget the last two digits of the numerator). The
instructions also mentioned something about that the section
immediately above the loading coil should be collapsed for
transmission. (Now why should that be? Does this mean that the
whole antenna above the loading coil should be collapsed, or
that just the single section immediately above the loading coil
must be collapsed, but the other sections above that can be
What the instructions completely failed to mention is where
should the loading coil be along the length of the antenna
when it is adjusted for a particular frequency? It only
gave a formula for what looks like overall length.
Does anybody have any experience using this antenna with the
HTX-202? If so, can you please fill me in on how to exactly
configure the antenna? (Maybe I should just return the
antenna and try to get a better one somewhere else?)
An E-mail copy of your follow-up would be greatly appreciated.
