I haven't looked, but I'm guessing that neither of the *mini* DIN series have much to choose from as far as connectors for 3/8" braided coax (RG213, LMR400, etc). They were developed to be the next g

Could you layout the typical matrix of connectors from the cell antenna down to what remains of the shed at the bottom.? 2G (GSM & TDM) used mostly simple N connector based transmission lines with t

Not really, they're both rated for -165 dBc, or something like that. BUT, the 4.3-10 IS supposedly less dependent on accurate tightening with a torque wrench (during mating with the female connector)

OK, it's a terminology issue. There is: 1) Smoothwall hardline. 2) Spiral corrugated hardline (like FSJ4). 3) *ringed* (my term) corrugated hardline (like LDF4). FSJ4 is #2, and water will travel und
