You need a 50ohm cable rather than 75ohm so that rules out rg59 & rg6. For that distance at uhf, I would recommend a rf cable commonly referred to as hardline. Don't know what is available in your country but something comparable to Andrews LDF5-50A which has a loss .83db per 100ft at 400mhz (uhf). As a comparison, Rg-213 has a loss of 4.8db at 400mhz (uhf). It really comes down to how much power your Motorola is putting out and how high and the gain of your antenna and what distance you need to cover with the uhf radio - realizing that uhf is a "line of sight frequency". As always, lots of variables.

well after a lot of research, i found that the Vitek outdoor mounts will work for us, the following mounts are the ones i bought, should have in a few days, they are being drop shipped to me... http://www.surveillance-video.com/vtptzwamo.html http://www.surveillance-video.com/vtptzcomoad.html btw, i just score the GVI KYB-300 PTZ/DVR controller, same ebay seller... Have you been able to get the KYB-300 controller to work with the gvi ptz's? My first attempt lasted 5 hours with no joy. Connecting the gvi ptz directly to the KYB-300 via 2 wire rs-485, I can get the controller to recognize the ptz at the correct camera number when I do the initialize command from the main menu but then when I switch to the ptz menu, no commands work. Am trying to use pelco d 9600 protocol and I am guessing since the initialize procedure recognizes the camera, the protocol and baud rate are good. After executing the initialize command and having the camera (address 02) recognized, I exit the main controller menu and select the ptz menu. When I enter camera 002 I get a very brief notice that the dome is not recognized or something to that effect but when I enter 002 to select camera 2 to be controlled by the controller a second time, it comes up as camera 002 pelco d with no errors but none of the ptz control function. So, would be interested if you have been able to control the gvi ptz's with the KYB-300 and if so, what is the trick? Thanks Finally had time to experiment a little more and was able to get the gvi ptz camera and controller keyboard working in "video plus" protocol mode which I guess is their home grown protocol but I need to get some variant of pelco protocol working as I have an everfocus ptz I would like to control from this gvi controller keyboard also. I tried pelco d 9600 and pelco d 4800 and could not get either to work. Any one have any suggestions on how to get the gvi keyboard controller to work with cameras set to pelco d (any baud rate) protocol?? Thanks
