Cellular extenders - 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.

you will need a cell-phone booster, like you might use to illuminate an office area that is below ground for instance. You need a solar panel and battery pack to supply it. Then on the antenna side you need an elevated position and a small yagi beamed on the nearest cell phone base to get the down-load link sorted. Finally, on the up-link side into the tunnel you need leaky coaxial feeder from Andrew Corp.
That should do it.
