[bars] RigExpert SWR analyzers?

[Guy DeMartinis]

Just a related antenna analyzer side note - I purchased a SARK-100 Antenna Analyzer for under $70 as part of my initial ultra-low-budget QRP HF station which includes a Bitx40 built into a lunchbox along with various MFJ necessities (dummy load, qrp tuner, etc.)... Less than ~$350 total including RF cable and materials for a home-made “shorty-40” dipole. I can’t say I’d recommend the SARK-100 or related versions as the quality from the Chinese companies that build them is hit or miss. Mine worked well enough for me to tune my dipole and some other antennae with noticeable performance improvements.... But now that I have an MFJ-874 on my bench I will go back and compare some SWR readings to see if the SARK-100 is junk... or not?

> Hello Andy,  Glad you found manual.  Yeah, would be good topic  for a lecture or article.  SWR analyzers, for sure so darn useful for understanding the complete electrical profile of your antenna.  An essential tool for all that might experiment with antennas and/or want to improve there system. Or monitor health over time. It really opens your eyes as to what is happening with your antenna whether your drilling down on a specific frequency and looking at reactances or looking at SWR plot and other parameters over a wide span.  If anyone whats to borrow my AA-230 Zoom, to check it out or just use to plot out an antenna, just let me know.  Regards, Dan WA1QZX

>> Folks - maybe this would be good for a meeting lecture or newsletter article - an SWR analyzer is a piece of test gear which can greatly speed up and simplify antenna setup. No need to fool with a transceiver and SWR meter. These things connect to your coax and almost instantly show you how well your antenna will resonate on a particular band or bands!

>> Great, thanks, Dan. I see they are not made in PRChina but the Ukraine. The Comet one is made in Japan. I don’t see a manual download area on RigExpert’s site...
