The antenna page in the docs has a section called “Testing Reports” and there’s a link to a Github repository and that will give you a whole list
For the T beam supremes I chose the Taoglas 2113 and it’s been solid. The ability to bend it 90 degrees lets me get lay it on the long side and keep it plugged in if I want
On the budget end yes but most boards in that price range won’t come with batteries or antennas. I have a few TBeam Supremes that totaled about $80 each when I set them up the way I wanted.
I’m a fan of the T1000-E!
Nodes with large antennas will get you more performance of course but it’s not easy to keep one of those on you. For the size it performs well with transmission, reception and battery and it can easily go wherever you go
Usually I’ll get that when the battery is too low. USB power/charging normally does the trick for me :/
