Why are power limits specified so low for dual-band and tri-band HT
rubber duck antennas? The conductors in the couple I saw surgerized
looked like they could handle lots more.

I am considering a mobile magnetic base that accepts SMA antennas,
but am deterred by the low limits for the duckies I would want to use.

The concept is that you transfer your ducky from the HT to the roof
when you get into your car. No problem with just the HT but not so
good with a QRP amp that outputs 30 watts.

Some of it has to do with the rather wildly variable impedance that an HT
antenna will present, but in general, HT's aren't high power devices, pretty
much by definition.

try pumping a kw into a 6" ducky on 2m and see how long it takes to be a
roast ducky... but it surely won't smell as good while cooking. oh, and
since most ducky's are not very far from the people using them you may get a
bit warm also.
