After much discussion purchase and evaluation nmo was a clear winner and the 3 8 inch version was my choice.
Installing nmo roof mount.
The center nmo had to be installed by feeding the wire through the hole from the top while the rear mount was able to slip into the hole from the bottom.
At the time of install the ex was about 4 years old so i didn t mind drilling a hole in the roof for the nmo mount and fishing power wires through the firewall.
The through hole mount was in.
As we move from left to right you will see a nmo mount to be used in a inch diameter hole with a length of coaxial cable attached.
So here we go with the steps taken to install an nmo 3 8 inch mount in my taurus roof top.
Both achieved the same result and i used a little bit of dielectric grease on the o rings to prevent tearing during the install.
Nmo a clear winner.
Nmo mounts come in various styles and the only difference is how the nmo connector is terminated on the opposite side.
I had installed a nice nmo mount myself for the quarter dipole antenna and wired the power directly to the battery with inline fuses.
