Checking the datasheets for 9913, 9913F7 and LMR-400DB shows no real
world difference at UHF. 2-3 dB (round number) at 500 MHz per 100'.
Most ops don't have the gear to measure that small a difference
reliably.
Personally would not use 9913 due to it's problems.
Never had a problem with F7. Used two 130' runs of LMR-400DB for 7
years in FL. Replaced the UHF run with LDF4-50A 3 years in. Difference
was remarkable. UHF and up for any significant length is worth the
time and effort to install hardline. Checked the VHF side on the
hardline, doing an A/B comparison. Could not tell the difference.
Next time I've got the sitemaster out, I'll try measuring the loss of
two different pieces of F7. One brand new, the other 20 years old,
exposed to the elements most of that time. Stay tuned.
Bottom line is that good coax with correctly installed connectors,
weatherproofed well will perform identically. Measuring the difference
would be very hard.
OTOH, while less quality connectors and coax may measure the same at
instillation, will degrade faster. (I.E. moving pieces like antenna
whips)
Hardline is cheep these days. New OEM connectors can be had very
reasonably and are almost idiot proof to install. (Older ones need
special tools!)
I hate doing things twice. These things tend to fail at the worst time.
Personal opinion: this is where pennies and sweat count.
Blah, blah, blah, blah.....

This has been an interesting chain of posts and I have copied it for
distribution at our club.? Thanks. I will continue to follow it.
However, to those out there that think that you can eliminate water in coax
with proper sealing, you are only delaying the inevitable, especially if you
live in a humid climate like New Orleans.? As an engineer familiar with the
psychometric chart, unless you can make your connection "air" proof,
anything except DRY air or DRY nitrogen positive pressure will allow water
to accumulate.? The theory is this:? at "relatively" high temperatures, air
in the coax holds more water as a vapor...invisible.? Normal atmospheric
pressure changes moves air in and out of the air spaces in the coax.? As the
day or season cools the air inside can hold less water vapor and some
condenses out as liquid.? (Think of the liquid condensation on the outside
of a glass filled with ice water.)? The liquid deposits itself in the air
spaces within the coax and "essentially" never leaves.? Continued cycles of
air pressure and humid air condense more and more liquid water within the
coax.? It is unavoidable.? It
may be possible to drain it out, but you won't get it all because of
capillary forces.
Without positive internal pressure, the enemy turns out to be the void (air)
space in the coax.? Eliminate the void space and there is no where for the
(humid) air to get into with changes in atmospheric pressure.?
I use LMR-400 with N connectors and "shelter" my connections with three
layers of waterproofing.? I say "shelter" because a true seal is
impossible.? I wrap from the bottom up to get "shingling" to repel liquid
water.? Water vapor (humidity) is impossible to avoid at a reasonable cost.?
When SWR's go up, the coax cable is over, and trashed.? Don't buy used coax!?

Bob,
Important to point out that the F7 variant of 9913 has no air
dielectric which got the original 9913 into trouble.? Also LMR cables
use aluminum foil shield covered with wire braid shield.? If exposed
to water the aluminum corrodes and gets quite lossy.? So wx sealing
is still necessary (two wraps of good electrical tape at
minimum).? Good electrical tape = Scotch 33+
I also seal with heat shrink tubing but often cover that with electrical tape.
LMR-400 is generally good to 432.? It is not anymore flexible than
Belden 9913.? For better flex consider LMR-400UF
(ultra-flex).? Slightly higher loss but better to go around az-el joints.
For long runs at 432-MHz one should consider LDF4-50 Heliax hardline
(1/2-inch) or lLDF5-50 up to LDF7-50.? Loss is higher at 1268.? I
have 15-foot run of LDF4-50 from my tower-mounted DEMI 144/1268 Tx
converter.? That gets the most power to the antenna and only needs
12vdc, PTT, and 144-MHz coax to input.

For 2 & 70cm I use LMR400.? LMR is better (in my opinion), in that
it's more flexable, 9913 can get water inside.? Unless coax
connectors are super sealed.

I keep seeing all these remarks referencing a "long run"... What is
considered a long run above VHF? 50 feet, 100 feet, something in between?
At what point should we be using 9913/LMR-400 coax or LDF4 hardline?

Yeah, really good question, Rick... I think it's a matter of both
frequency and what cable you're using, i.e. how much loss you're
getting. A Really Long Run of RG-8 may be several hundred feet or so
for HF, but only 100 feet at VHF, and 10 feet at 1.2 ghz. If the loss
is enough to matter, or if you need to spend a lot more money on coax,
then it's a Really Long Run.
A 3db loss, for most applications, is about where you can just detect a
difference. Don't forget to add in a little for the connectors. It's a
classic "half an S-unit" on receive, and the loss of half your power on
transmit. So, 100' of RG-8 type coax may be ok for VHF, but starts
becoming a problem at UHF and above. I.e. it's starting to become a
long run for UHF.
At least, that's how I would sum it up.

?Hi All,
As previously advised, AO73 will shortly be entering fullsun light and
already the eclipse periods are only 11/12 minutes every orbit.Current
predictions indicate that full sun will commence on Feb 6thand last through
until March 14th.
Our autonomous, on-board, scheduling system is based uponswitching modes
when entering and leaving eclipses, was not designed for this situations and
will therefore not besuitable for operations over the next few months.
In line with the recently published plan, AO73 was switchedto continuous
amateur mode earlier this morning and will stay in this modeuntil Sunday
night or Monday morning. We expect that this schedule will continue until
mid April. The next full sun periods are then expected to return again in
late August

Crawling from under my rock today to help a student find a satellite to tune
in, I saw CAS-4B. And it was a 36 degree pass. Tuned it in and heard lots
of SSB contacts and 2 CW contacts! Nice!
Being under my packet radio rock, I had not realized such a good linear bird
was at our latitudes. I guess I confused it with the packet ones only
workable from Florida.
Anyway, nice linear bird!
Back under my rock. Have to deliver PSAT2 in 2 weeks.
