RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

2.4Ghz antenna impedance test. - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

i had 30unit of old 2.4Ghz antenna, use for wireless lan and now want to reuse them ,but need to test whether those antenna is in good working condition or not.

so how do i test it and with which test equipment?

i can do a VSWR/impedance test using HP8414ET Network analyser. but is there any other tester which is cheap and small to do such test?

please recommend?

Some type of network analyzer is needed if you really want to know the performance. There are cheaper types as "sitemasters". They often work up to several GHz.

Regards

Jens
