impedance matching methods for 50 to 75 ohm line @ 2.4ghz - 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.

I would like to use RG6 quadfoil (75 ohm cable) for short runs (~100 ft) to a (50 ohm) roof top circular waveguide antenna for wlan links. Impedance matching one type of transmission line to another using a stub transformer section should be easy. Anyone have an on line source for formulas etc. to build one?
