Is that spec for the 91X of 16.7 dBi or dBd?
I ask because, I was reading on another site talking about this Grey-Hoverman - GH (GH10 rev2) Do-it-yourself antenna that gets great stable gain from low to High UHF of 14 dbi to 15 dbi, and 12 to 13 dBd.
So, the question is.. should I spend my time to build this GH antenna if I can give me more gain than 91XG ? Or does the 91XG still have more gain regardless?
I'd rather just buy the best gain antenna than make one myself (too lazy and too time consuming).
Here's the website to make GH antenna:
