FW: Travel antennas - outside with rig inside

Dr. William J. Schmidt, II
I've spent the last ten years or so searching for the right radio and
antenna combination for island jumping in the Caribbean.  I started with am
Icom 756 Pro II and dipoles (with snap-on legs) and used that combination
for several years.  The trouble is, the radio is extremely heavy, requiring
a Pelican case for just the radio and accessories (just making the 50 lb
limit).  Two months ago I tried a Flex 3000 + Laptop and a new YP3 -
portable 3 element beam/ tripod combination on a trip to PJ4... which from a
traveling standpoint was ideal.  The radio + power supply and laptop all fit
into a carry-on briefcase, while the antenna and tripod fit into a small
3-foot long duffel bag.  Unfortunately I found the radio to be very
difficult to stabilize without counterpoises, lots of RF chokes, etc...so
its history.  Enter my new K3 <advertisement begins here>.  I finished my
new K3 last Friday and used it in the IARU over the weekend with the
portable beam in the back yard, placing what looks like first in my section.
I'm taking it to J68 in 2 weeks (for two weeks) to put it through its paces
(including much needed RTTY contacts from J68).  Hopefully I can fit the
radio, power supply, and laptop in a carry-on.  For those of you who have
experience traveling with your K3's... I'd love to hear your experience
(what worked and what didn't).  I think, though, this combination will be a
winner...

I am out of town this weekend and brought my 28' random wire/counterpoise. I
have the random wire and counterpoise going out the window about 5' away.
The tip of the random wire goes up in a tree about 15' up. The counterpoise
goes out the window the opposite direction weaved through some bushes (to
keep off the ground) about 5' up.

The antenna seems to perform a ton better in a portable set up outside.
There are signals I can hear on 40, but they are much weaker than if I set
up outside.

Another note is the window frame is wood and cranks open. I pulled the
screen out to have clear access through the window.

Wire is #26 Silky Wire from The Wireman (my favorite).

I am thinking for this kind of set up I need to get the feedpoint OUTSIDE
the window. Right now the wires come through the window and attach to the
rig with a BNC-binding post adapter.

I believe getting the feedpoint outside the window requires a coax cable and
external tuner. Does anyone have any ideas on running the tuner inside the
rig that may work without coax?

Balanced feed lines will still detune through the window frame too, they
need to be clear. Maybe it would perform better than the wires I have now
though.

Steve, KC8QVO

Re: FW: Travel antennas - outside with rig inside

Hi Bill,

Me and my K3 have made two trips down to the Bahamas.   The radio, a small
switching power supply, and Heil Proset Plus headset, easily fit into my
roll-on bag.  There was even some room to spare for a good portion of my
clothes and assorted travel supplies.   My bag has an outside lap-top
compartment that was filled with my full-size Dell lap top.  

Next time I'd definitely go with a smaller computer.  Though on the my first
trip to C6A, a ran into a USB to RS-232 converter issue.  I think this was
likely linked to a driver issue with Vista.  For the second trip, the
lap-top was an older Dell with a real RS-232 port.  

Good luck with the new K3 and safe travels to the islands.

Best 73s,

Scott K2CK/C6ASH

KX3 - Arrives on Monday (7/23/2012)

I think CB Antenna would be very good choice for you. If you are going to choose a antenna for a car, then the best type is the top-loaded or base-loaded models. So just try any of these antenna & enjoy a good recetion..
