I'm using the Hustler CG-144 colinear antenna
with the radial kit. The antenna is 42' above
ground and fed with 35' of Flexi 4XL coax.

This antenna is apparantly a 1/4 wave phased into
a 5/8 wave and is working well.

My question is what impedance (SWR) would
this antenna sho on 446 mhz? I don't have a 440
mobile but I do have a VX-2R HT and I hooked
it up on 440 to this antenna and it seemed to
perform well.

I was running a cgt-144 and when I got a dual band mobile I used it on
440. The swr was higher than I liked so I added an adjustable grounded
vertical element about a 1/4 wave long about 1.5" away from the
CGT-144. The idea was to turn it into an open stub j-pole on 440. I
was able to get the swr below 2:1 on the repeater input freqs and in
theory the 1/4 wave 2m section (3/4 on 440) would radiate as an end
fed 1/2 wave on 440. It didn't seem to hurt the 2m operation at all.
It didn't work as well on 440 as the dual band Comet CA-2x4SR that I'm
using now but it did work.

I'm also planning on using the CG-144 with radials as fixed station
antenna now that it's been retired from mobile service.
