Nagoya NA771


Specs:

ManufacturerNagoya
TypeNA771
operating frequency144MHz and 430MHz
Gain2.15dB on 2m and 3dB on 70cm

This antenna is sold as an upgrade, so let's see how it does:
VNA test at 136-174MHz
Slightly more hopeful than the rubber ducky but still a bit… Flaky.
VNA test at 400-520MHz
70cm is still a bit sucky… Let's focus on the HAM bands in use:
VNA test at 144-146MHz
It sucks in the 2M band, perhaps 70cm is better?
VNA test at 430-440MHz
Nope, SWR at 6.5 or worse. Better range, but SWR eats up all the power.
