Upgraded antennae

I saw the OTR antenna here on Amazon and it worked like a charm

the inside antenna is also kinda weak

Poor antenna placement may cause interference with radio when turned on, which is user error

It works ok but is there like a stronger antenna for it that can be bought separate?

I installed this in a minivan for work and mounted the larger antenna (available separate) on the rear center of my roof and it gave me enough cable to get the booster to right behind my passenger side door which has a pretty convenient access door and space to mount

A better antenna will boost that (from what I've researched just plan on getting something better - the little magnetic mount doesn't do much - not sure why they bother).

I also can place the antenna in a car mount with the phone and it works great if you use bluetooth for music or talking.

I purchased an inside and external antennae for each vehicle to simplify moving it around vehicles

The larger wilson antennae is also recommended as it makes a big difference.
