[MRCA] AB-1241 - DC current rating?

[W2HX]

Yes that is a good suggestion. Would a series cap do the trick (isn't that whats in a dc block?) And if so, what effect would that have on antenna impedance and tuning it out?  
Thanks

I don't think you want to present DC to a virtual short, in any case, whether or not the transformer or the radio could accept/stand it..  Why not simply add a coaxial DC block to the transmission line and eliminate the issue, altogether.  Just a suggestion...

I am looking to use this with a radio that has a DC voltage on the antenna BNC, but current limited to about 30ma. Anyone have an opinion whether a constant 30ma DC current on this transformer would be tolerated by the transformer in the base?
