Brief Description: Garmin 430W & other GPS antenna mounting
|
|
I decided to optimize the mounting of the 430W antenna according to the best avionics advice I could find. The installation manual being first and and avionics shop owner second (Bill Betts, SparkChasers, KJNX). My thinking was 1) every source of advice has a bias 2) the performance of the 430W WAAS GPS being most important to me, 3) follow the avionics invested parties advice. So it's mounted on top of the cabin, right in the middle, far away from any possible interference, holes thru the cabin top, stuck out in the airstream.
The mounting required 5 holes. 4 being a bit larger on inside canopy skin to accomodate socket wrench.
The are 3 or 4 other GPS antenna involved. Here I just tried to find good locations that should perform satisfactorily, provide easy installation/maintenance and be aesthetically pleasing. So 2 are mounted along upper rim of the windshield - a location that's worked well on my Maule. 1 or 2 are going to be velcroed to the glare shield. No holes, nothing sticking out, nothing being visually unpleasant.
In total 3 GPS antenna cables and 1 power line have been run through center post with careful abrasion treatments at the both ends.
