Is there an antenna size limit for the LoPy4?
Please forgive the noobish question, but can I connect a fairly big antenna to the LoPy4 and a) not cause some kind of power problem and b) expect better results than the standard one that came with the LoPy? I bought a pretty big antenna today (about 1m high, 7 dBi gain, it can do 850/900/1800/1900/2100MHz frequencies apparently - I just want 864-866) but I'm a bit worried there might be some kind of problem if I try and use it.

@mk The physical size of the antenna does not matter. The electric properties count. If it has the proper impedance at the chosen frequency, it's OK.
I doubt it can do 850/900/1800/1900/2100MHz all at the same gain with a fixed length and all at a reasonable SWR.
