I can't remember the last time I did actually speak to someone on the CB
here that I hadn't phoned before to arrange it!

Perhaps it might be less confusing to some if we started referring to
the actual Carrier Frequency of any particular station...
For Example:

station for NHPTV who's primary ANALOG station is/was on analog CH11.

Ok, so I also could use some heliax.
Now, I understand fsj is the flexi but is it really that bad to install from
antenna to shack?
The reason I ask is there is some fsj4 on ebay. No ldf in any considerable
length.
I was looking at ldf1 but got quoted 1.25 a foot vs 190.00 for 250' of fsj4.
Try this websitehttp://www.surpluscoax.com/
Little differnce in FSJ$ and LDF4 other then slight change in loss value and
smaller min. bend radius for the FSJ. Big difference between LDF1 and FSJ4
size and loss figures.

For heliax at 'make offer' prices, check the equipment for sale listings
on the GNARC.org web page. This is good quality and some have
connectors already mounted. Shipping will be a problem Good
luck. It is good stuff especially for VHF and UHF

I really don't like using Superflex (FSJ) outdoors. The jacket on FSJ is
much thinner than it is on LDF, making it easier to get water in due to a
small nick. Also, the corrugation on FSJ is helical (spiral), whereas LDF
is annular (rings). The helical corrugation also makes it easier for
All this virtual channel and RF channel stuff!!
What would happen if a DTV receiver were within reception of

Or what if a DTV receiver were within reception of 2 different

Chris,
I'd use LDF for the long run, and FSJ for jumpers. Also, you'll need a
short jumper of RG-213, 9914, or similar at the antenna end to allow you to
rotate the beam(s). I don't think the FSJ is meant to be *THAT* flexible.
FWIW - I run 1/2 Heliax to my 2m/70cm stick at the top of my
Thanks!
I neglected to mention that the 70cm beam would be fixed rather than
rotatable.
Guess, I'll do the ldf outside and fsj or 214 inside.
Stinks being a cheapskate on a fixed income!

Virtual addressing is a pretty commonly-used thing these days in all sorts
of data networks. I wouldn't get too worried about it, the stations with
the clash would figure it out, perhaps using one of the -1 -2 type
identifiers to keep from confusing the little stupid $40 boxes, if there's

I posed this question to Tessco a few years ago regarding the use of FSJ
cable outdoors. Evidently there were concerns years ago regarding the
use of FSJ, or Superflex cables for antenna jumpers. I was assured that
any past problems have been resolved. I never verified this with the
Jim,
Why does any electronic component fail? It could happen for any number of
reasons. But, to answer your implied question, open diodes don't blow
fuses; shorted diodes do. If one of the diodes in a full-wave rectifier
opens, the output voltage drops and the ripple increases significantly.
You want the 1/2 FSJ for minimum loss in the line. the 1/4 cable will have
about twice as much loss. With Heliax cable larger is better, up to what your
pocket book can handle.
