For improving the -2 to -3db stock duck, I have a few alternatives on the ANTENNAS page at ...http://www.work-sat.com
The Diamond SHR=320A is a great antenna. Improved 2M and 440 performance on your FT-60R.
But for about thirty dollars LESS than that Diamond, we have the Smiley 270A. BETTER 2M performance than the $50 SHR-320A. And it is collapsible - so you only extend it as needed. A beefy spring in the based protects your HT's SMA connection.
The SMA-24 (and Pryme RD-98SMA) are also better performers than the stock duck. These "piano wire" antennas are great to coil up and transport in a Zip-Loc(tm) baggie - and carried in the glove compartment or in camping gear.
