There is only a .3 DB of loss difference between the regular and flex LMR400

LMR-400-UltraFlex.
Here is a link to the Times microwave coaxial cable calculator...

The TS2k handles full-duplex which you do not need. It also has some
an unfortunate birdie which may or not affect you (436.7950).
You could easily use some other UHF receiver or receiver chain with some work.
Notably you may have to remove the de-emphasis circuit or bypass it
by tapping into the discriminator directly; Some radios provide
such already and then you could easily decode 9k6 GMSK in software.

9913f7 has a solid dielectric. Conductor migration is a problem with
straight 9913, as well as other issues. Minimum bend radii need to be
observed.
PL-259 connectors can be applied to f7 with a plumber's torch.
Amphenol N's are easy install and easy to come by. Do look for the
9913f7 compatible ones as the center conductor is heavier.
I like Belden as quality is top notch. Flexible and long lived
product. Keeping work in the US? Priceless.
A 50' run is not much to worry about. Use LMR-400 DB (cost=free) for
the 130' home run to the shack on VHF. It needs no preamp. On the UHF
side, LDF450A does better, but needs a preamp.
Try Craigslist for bits of cable. I dug 300' of LDF450A out of a
dumpster. Still have 100'.
Tomato or tomato. Do take care as workmanship rules the longevity and
weatherproof qualities of the final product. All of this stuff works.
Install with a hammer? Not for long.

Message to US Educators (***)
Amateur Radio on the International Space Station
Contact Opportunity
Call for Proposals
Proposal Window February 15 ? April 15, 2017
The Amateur Radio on the International Space Station (ARISS) Program is
seeking formal and informal education institutions and organizations,
individually or working together, to host an Amateur Radio contact with a
crew
member on board the ISS. ARISS anticipates that the contact would be held
between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits
will
determine the exact contact dates. To maximize these radio contact
opportunities, ARISS is looking for organizations that will draw large
numbers of
participants and integrate the contact into a well-developed education
plan.
The deadline to submit a proposal is April 15, 2017. Proposal information
and documents can be found at www.arrl.org/hosting-an-ariss-contact.
The Opportunity
Crew members aboard the International Space Station will participate in
scheduled Amateur Radio contacts. These radio contacts are approximately 10
minutes in length and allow students to interact with the astronauts through
a question-and-answer session.
An ARISS contact is a voice-only communication opportunity via Amateur
Radio between astronauts and cosmonauts aboard the space station and
classrooms and communities. ARISS contacts afford education audiences the
opportunity to learn firsthand from astronauts what it is like to live and
work in
space and to learn about space research conducted on the ISS. Students also
will have an opportunity to learn about satellite communication, wireless
technology, and radio science. Because of the nature of human spaceflight and
the complexity of scheduling activities aboard the ISS, organizations must
demonstrate flexibility to accommodate changes in dates and times of the
radio contact.
Amateur Radio organizations around the world, NASA, and space agencies in
Russia, Canada, Japan and Europe sponsor this educational opportunity by
providing the equipment and operational support to enable direct
communication between crew on the ISS and students around the world via
Amateur Radio.
In the US, the program is managed by AMSAT (Radio Amateur Satellite
Corporation) and ARRL (American Radio Relay League) in partnership with
NASA and
CASIS (Center for the Advancement of Science in Space).
More Information
Interested parties can find more information about the program at
www.ariss.org and www.arrl.org/ARISS.
For proposal information and more details such as expectations, proposal
guidelines and proposal form, and dates and times of Information Sessions go
