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. 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. 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. 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. |

Rich 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. |

![]() I use the AEA units. I have the CIA HF analyzer and the VHF/UHF analyzer. I've had the MFJ (259 and 259B), AEA V/U (calibration was horrible), Autek, Timewave AntennaSmith (algorithm problems) and finally the RigExpert AA-200. It is a vector device, small, long lasting rechargeable batteries and allows for firmware updates in addition to archiving via the USB. For a portable device, this one wins hands down in the under $1K category. Dale W4OP |

Well I guess everyone else hates theirs.
Darn, mine works just fine. Has saved me a ton of time doing tuning work. Guess I will just ignore the rest and keep using it. |

I've had my trusty MFJ antenna analyzer for many years, and couldn't think of being without it. Definitely one of the most useful tools a Ham could have around the "shack" Regards, Joe Cro N3IBX |
