Does anyone make a telescoping HT antenna meant to operate (1/4 wave)
over a broad band of frequencies with marking for those frequencies?

I've seen one or two such on a dealer's table at a local hamfest,
although I'm not sure that they come pre-marked - the package gave
instructions for the number of segments to collapse to achieve
resonance on 220 and 440. I think one was made by ADI and/or Premier
but I can't be sure.

Most HT's can be modified to operate outside the amateur bands, like on
GMRS, MURS, FRS, etc. But I don't like doing this without a proper antenna.

You really shouldn't do it (well, at least, not transmit) even _with_
a proper antenna. Very few, if any amateur-radio HTs are certificated
for transmission on those bands, and using an "opened-up" ham HT to
transmit (even if you have a suitable GMRS license) is a rules
violation which could cost you your amateur ticket.

FRS and GMRS have very strict technical rules about the frequency
accuracy of their oscillators due to the tight inter-channel spacings,
and it's likely that at least some ham HTs are too sloppy in design
(or too poorly calibrated) to hit the frequencies accurately.
