Looking to get a (highly recommended) NAGOYA NA-771 37cm "Dual band (2M/70cm) handheld antenna" for my Baofeng UV-5R.
If my math is correct - this is about a half-wavelength antenna for 70cm, but doesn't seem to correlate to anything for 2m.
What does this mean? Is it really good for 70cm but no so much for 2m, or am I misunderstanding the principals/construction of this antenna. (Also, it's just a handheld antenna, so it's not a "dipole" nor does it have an evident "ground" - so I might not just understand what it "is").
