I have no experience with triplexers but it sounds like a bad idea to
put 4.5KW (3 bands QRO) through an N connector. I agree, use DIN
connectors.
7/8" RFS hardline (LDF5-50 knockoff) is $2.50/ft so what is that in
comparison to the cost/db of tower + yagis + rotators and then add
triplexers, BP filters? Big hardline feedline yields cheap db's in my
view, lasts forever, and shields better. My goal was <1db amp to
feedpoint loss. LDF5/AVA5 for 20/15/10 and LDF4 Heliax for 80/40. Some
big guns use 1 1/4 or larger to their towers.
The spools of larger sizes often go cheaper than 7/8 from the surplus
dealers. Still cheap even if a right size DIN connector costs $100.

I have a similar problem at my new QTH. I'm considering a few products
from Low Band Systems. They offer a variety of multiplexers depending
on what bands you'd like, but I have not yet personally used one or
even seen one in person. DX Engineering has some of their stuff, the
rest is at http://lowbandsystems.com/collection/multiplexers.
Maybe someone else in TowerTalkia has a review they'd share. I'm
especially curious how it works when you're drilling 1.5kW x3 (in the
case of a triplexer) down a single feedline.

I am looking at a possible location where the antennas will be 500 feet - maybe
a little more from the operating location. Is anyone aware of a 5 band (80-10
meters) multiplexer that would allow simultaneous operation of 5 radios via one
coax to a tribander + 40 and 80 meter dipoles located 500 feet away?
Thanks and 73,
