The reason I'm asking is that 'm considering putting up a 10 dipole in a
portable location.

My first week with my HTX-100 mny years ago was a blast, and I've
enjoyed operating ever since. Most frustration: Hearing a French
Polyneasia at 10 over S9 and being unable to get through due tyo a
couple of hundred Califonians (onw skip zone closed) with beam antennas
and kilowatt amplifies. 25W into a dipole just couldn't cut the mustard.
