Who has short clean LoS to Cougar?
Hi all, 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. 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. Fun times! Let me know if you can help, --Bart

This picture really sucks, since it was taken free hand with my iPhone, but it sort of give you an idea of the shot to the radio towers. This is taken from my front yard, the red 'dots' are the lights on the towers to keep planes from flying into them. http://www.ku7m.net/drop/CougarRadioTowers.png It is suppose to be clear tomorrow, so I'll try to grab a better picture in the morning.

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: http://www.avalonamprepair.com/hughes_1177h-series.jpg http://www.avalonamprepair.com/hughes_1177h-series.jpg 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. --Bart On 10/16/2013 8:06 PM, Kenny Richards wrote:

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. Sent from my iPad

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. 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. --Bart On 10/16/2013 11:10 PM, Kenny Richards wrote:
