I'm not sure you understood the "Tech question" properly. There's very little difference between "N" and "properly installed, good quality, UHF" connectors at 2 Meters, and in most cases, on 70 cm, and much commercial and Amateur equipment still use UHF connectors through the 70 cm range. Above that, there is a concern about maintaining a constant impedance through connectors, which the UHF series does NOT provide. At or below the Amateur 70 cm band, there is little advantage to using type "N" connectors, save for the inherent "weather-proof" assembly of most (but not all) type "N" connectors. (At least, those with Mil-Spec UG-21xxx designations are supposed to be highly weather resistant.) It certainly won't hurt to use "N" connectors, but the co$t/advantage ratio usually makes the cost greater than any advantage gained, at least through 2 Meters, and even 70 cm. Above 70 cm (~450 MHz) I wouldn't use UHF connectors, regardless of purported quality; I would use only "N" connectors, but again, properly installed, and from a known, quality brand. (Such as Amphenol, Kings, or a few others.) "Cheap" import "N" connectors may be worse than using UHF connectors above ~100 kHz... Connectors are a dear part of your installation, and can be a bear to replace if they fail; don't try to scrimp and save a couple of $ on inferior coax connectors of ANY type. One trip up a tower, in the dead of winter, will make you wish you hadn't saved a couple of $ on inferior connectors. BTW, I'm a certified ARRL "Instructor," and I can't find any part of the Tech OR General question pool referring to a "NEED" to use type "N" connectors, at least not on 2 M or 70 cm. I personally have equipment through 1.2 GHz, and the only time I feel a NEED to use type "N" (or BNC for low power) is on 1.2 GHz; I don't find good quality "UHF" connectors are unacceptable even at 70 cm. I certainly wouldn't modify any of my equipment just to accommodate type "N" connectors, although I might use them (due to weather resistance) if I were constructing my own equipment or antennas, but then, only on bands above 2 Meters. As far as coax is concerned, your best bet for runs under ~100' would be a version of LMR-400; there ARE good equivalents made by Belden, as well, if properly installed. If you are installing a vertical antenna , then standard LMR-400 will be adequate. If you are anticipating using a rotatable antenna, they you would need at least a short section of more flexible cable (Such as LMR-400UF) to allow for the movement of such an antenna; the standard LMR-400, or many versions of Belden 9913 are quite stiff, and would not allow for rotatability.
