Re: Wimo 13cms aerial VSWR

Conrad, PA5Y

Alwyn the S331 is indeed useful and unlike it's cheaper predecessor the S251,  has an acceptable frequency accuracy the S251 was 200ppm I seem to recall which is not great on 13cms. However where can you get an S331 for a few hundred pounds? 

I would sell my IC-7300 to get an S331!

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.
