What do you think of the antenna analyzer?
or do you like some thing else?

They do not work well in high RF environments such as many repeater
locations where there are other transmitters close by.



What Does??


A Bird 43 does nicely.


Even after 30 years in the business, I still see people hook up their $50K
service monitors to a site antenna and blow the input.


I have a friend who lives at a pretty high location (3000 ft MSL) and
about 4 miles from a broadcast (TV/FM/Commercial) site at 4000 ft. He
cannot use an MFJ analyzer at his house because of the induced RF.


There is not much use of setting up HF at a repeater site, because
ionospheric propagation is the predominant mode, also it puts you line of
sight to a whole lot of man made noise.


The OP never mentioned anything about frequencies. Just a question
about the analyzers in general.

Although these things claim to work at VHF, I notice they have an SO239 so
how seriously do they expect to work at those frequencies.


They also claim to work at UHF. While the SO239 is not the best
connector for those frequencies, you can get by with it. Motorola
manufactured a bunch of radios with SO239 connectors that used the
800Mhz band.


Mine saved me lots of time setting up my 9band Butternut vertical, but they
eat batteries, so I cobbled up my cordless drill battery to work with it on
the roof.


I use the AEA units. I have the CIA HF analyzer and the VHF/UHF analyzer.
