Any ideas on this?

heat shrink provide suitable insulation to prevent corona from
starting the bush on fire? Is there a better idea? I will be
using PTFE (Teflon) insulated wire.

a 1/4 inch hole in the aluminum window frame. I was going
to feed it through a plastic straw to prevent chafing and
possible short circuiting. Any suggestions on the best way
through the hole to prevent any problems?

I'd ask the management but I don't want to trigger them
into realization that future QRM will probably be
emanating from my 'shack'! I plan to work the world
while remaining invisible to those around me. If asked,
I'll just explain that the wire is an antenna for my short wave
receiver!!!!

This is the first time I've had to use a store bought rig!
Until now I've either had modified surplus or burned out
rigs which I rebuilt. I've always been an advocate of
low power, but real QRP is new to me too -- and I equate
it to the difference between dynamiting ponds and fly fishing!
Time will tell! :-) When I became ill I gave away all my
50+ years accumulation of valuable ham radio equipment,
tools, test equipment, and books -- collectively A.K.A.
"Junk". It's fun starting from scratch -- at least my shack
is not a terrible mess -- YET!

Do folks still mail QSL cards? Or can I settle for emailing
a graphic equivalent of my own design? I've been off the air
for a couple years now and think that things may have changed
while I was out of the picture. This is not a big problem as
printing and using the local buro shouldn't be too much of
a problem. The hundreds of rare QSL's coming into my
mailbox my invite unanticipated curiosity from the
management.

Thanks in advance for any ideas you may have. This
is the first time I've run through a metal window frame or
dropped the wire into and among the branches of a tree.

Calgary, is that right? Do you need to allow for snow, ice and wind in
designing your antenna?

I have had good luck while camping, with transparent fishing line at the
end of antenna wire. It has some stretch, is easy to tie to tree limbs,
etc. And a spool will last forever.

Unless you have other ideas for the window hole, put the wire through
and use a hot glue gun to seal the hole. If you can reach both sides of
the hole, do the same on the outside. RTV also works.

Good luck. Paul, KD7HB

Thanks Paul,
I never thought of it, but some monofilament (I'm a sport fisherman) will
fill the bill. Until now
I've always used parachute cord but don't have any anymore. I plan on
sealing the hole at
both ends with RTV. Hopefully the wire I use will stand up to the harsh
Alberta winters,
all my antennas have so far, but if need be I can readily replace the wire
with very
little effort. According to my calculations, which include Murphy's Laws,
the
antenna should stay up until minus 40 degrees, a windstorm, and blowing
snow occurs -- and according to Murphy it will all happen in the middle
of a QSO with some extremely rare DX!

Personally, I have always found Murphy to have been somewhat of
an optimist!

Thanks again for the suggestion,
