Hi, Jon
Are you operating mobile or fixed with that Ham Stick? Keep in mind that
it's essentially a quarter-wave vertical and needs to "work against"
something - such as the body of your vehicle (with the coax bonded to the
vehicle body at or very near the base of the antenna) or a good set of
radials. For fixed locations, a horizontal dipole is a far better choice for
10 meter SSB/CW work. Ten meters has not been open very much lately, but the
local HCRA net should give you a good idea if it's working at all. Remember:
A good SWR does not necessarily mean you're getting out.
The Arrow is a cross-polarized antenna (horizontal on one band, vertical on
the other or something in between depending upon how you orient the
elements). It's designed primarily for satellite work.
For 2 meter FM repeater work, the 2 meter (longer) elements should be
vertical for best results. For 2 meter SSB/CW work, the 2 meter elements
should be horizontal for best results. Same for 440 FM vs SSB/CW (assuming
the antenna has a sufficiently broad bandwidth). Incorrect polarization
could account for the experience you've described - being able to hear
signals okay without their hearing you.

I finally got all the parts and pieces to connect a 10m Hamstick; an
Arrow Dual Band and a 1.2Ghz antenna from Directive Systems in
Lebanon,ME...
This morning I hooked up all the antennas to their respective
connectors on the back of my Kenwood TS-2000X and you know what... I
don't hear a thing on 10m; apparently my 2m and 440 signals aren't
getting very far since I can hear guys talking clear as a bell on
146.715... but they never reply to my 'listening' call.
It seems strange that I can't even pickup the beacons on the various
bands... Can anyone out there provide some guidance and perhaps setup
a time to check 10m.... I will try the net this evening on 28.375....
I did get to make some nice contacts while in Deer Isle, ME last
weekend including one on 2m that was 80+ miles away... I was on a boat
out in the Atlantic at the time!
Namaste & 73s,,
