<div class="moz-cite-prefix">It doesn't need to be elevated, it just
needs LoS to cougar and be capable of housing a dish + amp for a
few weeks without theft/problems. Weatherproofing might be as
simple as the Inverted Bin Mounting System (IBMS(tm)). A couple
feet of feedline should be OK. What's the loss on your hard
line? I think I calculated about 40% (4W) power loss in a 35ft
section of 1/2" Heliax. Microwave transmission is not a business
we wanna be in. Waveguide is the only sane technique, but that's
really expensive.<br>
<br>
I wish the amp was smaller so that it was more convenient to use
it, but is isn't yet. I'm working on it. Just unloaded the wire
bonder off the trailer. It'll bond up some nice microwave dies
for compact high power amps.<br>

<div>Your not wanting much. So we need an elevated location that
can also house a un-weather proof amp? :-). I need to think
about this, is there a reason we can't use hard line ? I may
have a 35 foot run of 1/2 inch that just needs a N connector put
on one end. Still not great at 6ghz, but better then LM400.</div>

<div class="moz-cite-prefix">Good stuff! Try to grab it from
a place where we might leave a dish, and house a
yet-to-be-weather-proofed amplifier. *Short* runs of LMR400
might be OK, but the attenuation/ft is really high @ 6GHz.
The amplifier looks a little like this, and it makes noise
when it runs:<br>

<br>
We'll dangle a 5SHPn modem with a 20dB attenuator off the RF
INPUT port, and then attach the antenna to the RF OUTPUT
port. We'll have to turn down the power on the radio to
just +20dBm so as not to saturate the amplifier. It only
needs about 0dBm for full +40dBm output.<br>

Hi all,<br>
<br>
Is there anyone on list who lives
close to Cougar and has a clean line
of sight to it? Issaquah highlands,
Sammamish plateau, etc? I'm looking
for a volunteer to point some
equipment @ Cougar towers from a
nearby ground location. We'll leave
it installed for 2-4 weeks to run
the experiment.<br>
<br>
Oh, and the experiment has to do
with scatter communications,
utilizing radio towers as
reflectors. You'll get a 30dBi dish
and a 10W 6GHz amplifier for a
whopping 10kW EIRP. It'll send out
beacons with your callsign, and
we'll try to pick them up around the
Puget Sound.<br>
<br>
Fun times!<br>
<br>
Let me know if you can help,<br>
<br>
