At these freqs, 75ohn RG6 cable is usable with reasonable loss. maybe
75ohm cpe is the way to go... Chuck McCown - 3 wrote: 75 ohms. Someone will spin 50 ohm models. Or just put up with the minor VSWR. ----- Original Message ----- From: Blair Davis To: WISPA General List Sent: Tuesday, November 18, 2008 5:22 PM Subject: Re: [WISPA] TV Whitespaces PtP BackhaulLook at the BLONDER TONGUE BTY-10-U UHF single channel units Third photo down on the left.

So are we looking at an extra trailer behind our install trucks to carry an 8ft x 6ft yagi as well as 10 foot tv tower sections to get it up high enough and away from the house.

Same band, same size antenna for same gain. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "Steve Barnes" <[EMAIL PROTECTED]> Sent: Monday, November 17, 2008 9:45 PM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] TV Whitespaces PtP Backhaul Even in our area in eastern Indiana there is lots of 5.8 still available for PTP. 700 PTP is not necessary in my opinion. I am concerned about 700 Mhz antenna sizes. Aren't sectors going to be huge to get the 4 watt at the antenna? I am also concerned about the CPE Panel size. Going from a 15" Panel to a 20" panel gives us a lot more wind issues at the client. Don't get me wrong I am excited about the whitespace out come. I appreciated the work of the Whitespace committee. We have tower owners who are concerned about the sizes of our antennas now. Change from a 12 foot 900 Omni to a 16+ foot 700 will not get rave reviews.

To those of you that understand the extreme rural environments... Is this at all necessary? I don't see why it would be. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ------------------------------------------------------------------------ -------- WISPA Wants You!
