Re: Wimo 13cms aerial VSWR


Just got into microwaves here, I use both a cheap Chinese vna, and a combination of an rf bridge/noise source/sdr receiver. They both show pretty close agreement up to cutoff of the rf Bridge assembly (1.5 Ghz). Would be interesting to compare them beside a decent setup, suffice to say swr lights on my sg lab transverters (2.4 and 1.3Ghz) are always happy. 
As regards the wimo, I would say do check all the elements too. I have a 37 ele recently aquired for 23cm. Two of the elements had been placed in wrong order (might have been previous owner!), causing the useable bandwidth to become very narrow.

Dear All,

Yes, I have always liked the HP8753, but they are not cheap.

Although it is only a scalar analyser, the Anritsu S331 is pretty useful for aerial adjustment.

Also, it’s intended for use by riggers, so is compact lightweight and battery powered, so handy in the field.

A few hundred pounds on e-bay is the typical price.
