I'm using this type (26dB, N Connector) on my balcony (South).
It's mounted on a 1m waterpipe, that is "stripped" to the balcony fence.
I initially bought a 40dB , but had to change to 26dB , due to too much
I use a Tbolt, that have 75ohm impedance , and am using about 25m quad
shielded 75 ohm , quality sattelite cable from the balcony to the Tbolt.
I'm using a N-->F adapter at the antenna end, that makes it super easy to
make a diy F-->F connector cable.
I now have installed a quad active antenna splitter (50ohm) , using the
same 75ohm cable , and a F-->N adapter at the splitter end. And see no
noticable problems using 75ohm cable there.
