Did a quick install for MXT275 with MXTA26 6dB antenna and MXTA24 low profile antenna cable (Note, this cable's FME/UHF connector can be separated to go through firewall easily)
The SDHQ ditch light mount is perfect for the job. Very nice fit and just enough space. // Absolutely no affiliation with SDHQ whatsoever.
Rest of the install was pretty straightforward:
1) hardwired to battery for ignition power with Add-a-Circuit Fuse Tap Adapter.
2) Mount the antenna using SDHQ ditch light bracket. Note the NMO connector requires a 5/8' hole; you need to enlarge the mounting hole on the bracket.
3) followed this video from Gamiviti to fish the wires through firewall. I don't have the silicon spray shown in the video, just rubbed a bit of butter, works perfect.
4) Did glovebox install. Remove the glovebox divider, open the cabin air filter door, fish the wires. I drilled on the cabin filter door, but you could drill on the glovebox too
