I have a confession to make; I've always wanted an outdoor
antenna, but I was never either allowed to (when I was a kid)
or wasn't pratical do run one. Well, I now have the ability
to run one outside, but there are some questions I have about
some of the gagetry that is available these days.
Since I'm planning on running a random wire until I can figure
out a more permanent location for a trap antenna that I'll
build (assuming that I still have that old article from Pop Comm
(or was it Audio?) lying around), I'm not so concerned about
the antenna itself as some of the other goodies.
First, the coax. I noticed that Rat Shack was running a special
on their RG-58U coax for $0.11/ft, but I also know that RG-8 is
has better attenuation numbers. My run of coax is about
60-70 ft or so (at least initially, I'll probably remove some of
the built-in slack in my estimates once I'm satisfied with where
the antenna will be). Should I worry about attenuation for the
HF bands enough to use the RG-8 over the RG-58??
Second, a lightning arrestor. Are those Alpha Delta Transitraps
as good as advertised, or should I stick with a regular gas
discharge variety??
Third, has anyone run an external antenna to their Sat 800?? I'm
curious as to your setup, since it's a plastic case and the old
ground connection that I was used to on my old Icom R-70
isn't around, so I was wondering if anyone bothers to try to
ground the outer jacket of the coax. (Yeah, I know that that
ground on the R-70 was for the casing, and that this means we'll
open a can of worms here, but I figure I'd ask anyway.)

CONSIDER BUILDING A "LOW NOISE" ANTENNA:
Try building an Improved SWL Random Wire Antenna that uses a
9:1 Matching Transformer (Balun / MLB) then you may not see
any real 'improvement' in your receive signal.
This is the so called "Low Noise" SWL Antenna.

ABOUT THE "LOW NOISE" ANTENNA 'DESIGN CONCEPTS':
A Random Wire Antenna Element coupled via a 9:1 Matching
Transformer at the Near-End of the Antenna with a Ground
Rod and Coax Cable Feed-in-Line to the Receiver. This is
the basic SWL Antenna that uses the "Low Noise Antenna"
'design concepts' that were popularized by John Doty.
