Recommended RF cable RG type for WiMAX - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Hi ssabir
The question you raise is too general to give advice because there are many RG cables with low loss.
You need to do a loss budget for the system you plan to implement based on transmitter power, antenna gain, bandwidth, receiver sensitivity etc. From this, a maximum tolerable loss in the feeder cables can be estimated. Based then on the physical layout constraints of distance between electronic units and the radiating system, you can calculate the maximum tolerable loss per meter. From that you look up the data sheets to find the nearest match.
Hope that helps.
