Jennings RJ1A vacuum relay measurements

[W1VD]

Normally used for high power QSK cw operation ... these relays might be suitable for use in high power AM transmitters. Small size, reasonable price (on ebay) and serious power handling capability at HF. 

Recently made isolation and impedance/return loss measurements. Info may be of interest ... http://www.w1vd.com/RJ1A.html.

As always, professional grade measurement data and well presented. Thanks for sharing.

Thanks for the informative data Jay.  As you have noted, it should provide a good solution for your 6 meter project in addition to offering a great solution for use on HF.
