I have been using LMR-600 UF for 15+ years.
Its great.
I no longer worry about coax loss for 2m and 440.
My runs are 100 feet.
I work EME with a Single yagis.
Single 2meter M2, 20 element CP
Single 440 M2 44 element cp.

I use 9913F7. Works great.
There are a number of alternatives. Some of the stuff is great for a
year or two, then the jacket degrades. Brand names USUALLY get a
reliable product.
Hope to hear you on the air.

I'm doing a "Satellite 101" presentation for two clubs in the next two
weeks.
So that I don't have to re-invent the wheel, does anyone already have an
"AMSAT Vision statement" (or something similar) slide(s) in PowerPoint
and/or OpenOffice Impress format, so that I can incorporate it in my own
pre-existing presentation?
Thanks

For the VHF/UHF contest in September, there will be a group active
locally...and running 1.2 GHz!
Since L-band is active on AO-92, and I have the equipment - but no
antenna - I'm looking for an L--band antenna that I can use both
terrestrially and for the birds.
My preference is for M^2, but both yagis on their website are a little
larger than what I'm looking for - but they are still under consideration.
Does anyone have recommendations for another brand, or have an appropriate
one for sale? (I wish I had bought some of those loop yagis which were
prominently displayed in Ball Arena at Hamvention in the early 90s...)
(I'll be at Shelby NC Hamfest this Saturday (mostly at the AMSAT info
table), in case someone is attending who has one and wants to bring it .)
Thanks

Comet CYA-1216e is a nice antenna, and what I use, but a little pricey.? DX

Message-ID: <1535405064.598994622@???.??.???>
Content-Type: text/plain; charset=utf-8
AMSAT-EA will be trasmitting its special call AM1SAT via all active
satellites from Septembre 10th to September 17th as part of the IV RadioHam
Fair IberRadio 2018 activities. IberRadio is the biggest event for the ham
community in SouthWest Europe and will open doors September 14th and 15th .
Learn more about IberRadio at http://www.iberradio.es. AM1SAT callsign will
be active from a minimum of 14 differents grids during that time to help
satellite operators to collect as much EA locators as possible.
As part of this activity and in order to promote the participation, AMSAT-EA
is sponsoring the AM1SAT Special Award in two categories: SILVER and GOLD.
AWARD RULES
1.- This award can be requested and issued to any licensed amateur station
and also SWLs
2.- Will be valid contacts all those done via AMSAT satellites from
September 10th 2018 to September 17th 2018 in all transmission modes.
3.- There are two different requirements to get the awards, depending of the
applicant location.?
Applicant in a EU entity.
To get the award in its SILVER category, the applicant has to contact AM1SAT
in 5 different grids (We consider ?grid? as a 4-digits main locator. For
example IN71, IM68, JN00, etc). To get the award in its GOLD category the
applicant has to contact AM1SAT in 10 different grids.
Applicant in a NON EU entity..
To get the award in its SILVER category, the applicant has to contact AM1SAT
in 2 different grids (We consider ?grid? as a 4-digits main locator. For
example IN71, IM68, JN00, etc). To get the award in its GOLD category the
applicant has to contact AM1SAT in 4 different grids.
4.- There is no need of paper QSLs nor EQSLs to ask for the award. When the
applicant gets the requirements, he has to send via email a log with the
QSOs, listing his callsign, name, and QSO data (Date, GMT time, frecuencies,
mode, received grid and used satellite). Also we need the applicant email to
send the award. The awards will be send, latest in 2 months and only in PDF
format, free of charge.
5.- Logs and any question about this activity must be send to
eb1ao@????????.??? .
6.- Logs must be received by October 1st 2018. We will consider the AM1SAT
operators logs as the valid ones to check and cross the QSOs. Disputes or
open issues will be solved by AMSAT-EA committee.

Message-ID: <5B847106.2020004@?????.???>
Content-Type: text/plain; charset=windows-1252; format=flowed
Antenna configuration:
Yeasu Azimuth and elevation rotor.
Solid fiberglass horizontal mast, 2.00 diameter, 14 feet long.
M2 2-meter (20 element) on one end, M2 440 (44 element) on the other end.
I installed two 80 foot sections of LMR 600-UF from the shack to top of
the tower.
I have the option of installing a tower mounted preamp, but just added a
Female to female N-Connector at this spot.
Preamp are in the Shack.Higher loss, but I have not Fried a Preamp in 15
years.
I installed 2, 20 foot sections of LMR-600-UF is used to go around the
AZ/EL Rotor to the antennas (one for each ).
LMR-600-UF is flexible enough to be used around rotors.Just following
the bend radius rules for this cable.
Issues:
I used high quality UV-stabilized tie wraps to attached coax to Masts
and antenna booms.
After 10 years of usage, my SWR went bad on the 2-meter beam.
The vibration and flexing of the antenna boom and rotor masts caused the
tie wraps to "SAW" through the outer layers of insulation on the LMR-600-UF.
I had to replace the two 20 foot sections of LMR-600-UF.They were full
of water.
Also the 2-meter tuning stubs were also Sawed through by the tie wraps.
I replaced all of the 10 year old damaged cables.
I reinstalled by using Spiral-Wrap over the sections of coax that were
going to come in contact with tie wraps.
I would add about 4 inches of Spiral-Wrap and then UV black tape to hold
the Spiral-Wrap in place.Then I installed 2 tie wraps over Spiral-Wrap.
New Rules.
Never use a Tie-wrap on a bare section of coax insulation (if there is
any chance of vibration or flexing).
Always cover the coax insulation with Spiral-Wrap to prevent the
tie-wrap from sawing through your coax.
