Re: [WISPA] Attenuation of polycarbonate or acrylic at 5.8Ghz ?
See if you can find the dielectric constant for both materials and pick the lowest one. The best material I found was made by a company called Stealth Technologies back in the 90's. I had Andrew perform tests on their range with a variety of materials including 1/4 PVC, 1/4 fiberglass, 1/4 ABS Plastic, and the stealth sandwich which was a 1 thick piece of closed cell foam between two 1/8 pieces of ABS. The stealth material won out. The fiberglass was the worst. The PVC and ABS were about the same and presented only a small amount of loss. These were at PCS frequencies right around 1800 MHz. You have to figure a bit more loss the higher frequency you go. Regards, Cameron On Wed, May 25, 2011 at 7:28 PM, lakel...@gbcx.net wrote: *Not gonna be a problem.

Re: [WISPA] Towers
Ditto on that Rick. We had a Trylon T200 loosen a set of leg bolts over about a year and fold over after and ice storm followed by high winds. We torqued the bolts to mfg specs, but being on a high windy hill, the constant oscillation loosened the bolts on one leg at about the top of the second section. And, you are right, they are uncomfortable to work on for extended periods with no flat cross bracing to stand on. A neighboring wisp had the same tower fold over on them a couple months later. I would not use them again unless VERY lightly loaded and under ideal conditions.

Re: [WISPA] [Wisp] WISPA National Disaster Committee - Seeking Volunteers
I was talking to the tower owner and I think they would welcome any contacts for tower manufacturers that could get them a comparable tower fairly quickly. The specs on this one are : 500ft tall, 36” face, I think about 2” solid steel legs. Thanks, Chris Hudson Hudson Technology Solutions, Inc.

Re: [WISPA] [WISPA Members] WISPA National Disaster Committee - Seeking Volunteers
Victoria, I have made this suggestion a couple of times to various members of the board over the years and I will do it again. In the days following hurricane Katrina members of WISPA discovered how difficult it is to help in disasters when you are not part of a recognized group in the emergency management system. Many WISP's are also Amateur Radio operators (hams's). This group is recognized by both the FCC and emergency management agencies as a participating agency and has memorandums of understanding in place with non-governmental organizations (NGO's) such as the Salvation Army and the Red Cross through their national organization call the American Radio Relay League (ARRL www.arrl.org) . This group of people typically belong to the Amateur Radio Emergency Services (ARES) and/or the Radio Amateur Civil Emergency Service (RACES). They are trained in providing disaster communications and are an integral part of the Incident Command System. They have a national training program and a full-fledged field organization nationwide. I would recommend that WISPA establish a memorandum of understanding with the ARRL and do our best to integrate disaster efforts outside of helping individual WISP companies. Being able to establish internet and/or point to point Ethernet connectivity is very important after a disaster. WISP's can quickly do this. Being part of a recognized organization will help eliminate the problems associated with trying to do so in a disaster area. I will help with this committee, you should reach out to the ham wisp list that was created to see who else from that group would like to participate.
