Posted: Mon Sep 11, 2006 9:48 am Post subject: Antenna locations in an RV9

I'm getting ready to install my antennas in my RV9 - COM bent 

whip and a TPDR blade.  I'd like to mount them just forward of 

the wing spar outboard edges of the cockpit floor.  I think I 

can just keep the connections under the foward center section 

covers.



I get the sense that most people go behind the wing spar - 2 

advantages of mounting forward is that i) you don't have to 

pass the wires through the center section and ii) it gets a 

little more distance between the antenna cables and the wing 

strobe head cables.



Any good reason why I shouldn't mount them forward of the 

center section ?

Closer to engine noise,



Not much room between the floor and underside of cover...Have to allow

enough bend on the cable...Or use a right angled adaptor.

Yup, right angle adaptor was where I was going ... engine noise 

is a very good point ... thx.

Gerry,



I put my transponder antenna in the center just in front of  the spar in 

my -6A. Behind the console, there is no need for a right angle adaptor. 

My two comm antennas are left and right in front of the landing gear 

weldments well outboard of the centerline. There, I used right angle 

adaptors. With sound proofing material between the ribs of the floor 

about the thickness of the rib height, the adaptors seem adequately 

protected. With a carpet over the soundproofing material, the cable lies 

between the carpet and soundproofing material. I have about 100 hours on 

the aircraft and both transponder and comms work well.



Regards,



Richard Dudley

Interesting, thanks for the comments.  Question - with the 

transponder in the center are you seeing any affects of 

heat/dirt from the engine exhaust pipes ?

Gerry,

 The only effect that I see is some oil accumulation from the breather.  I have not yet eliminated the oil on the undercarriage even though the breather is immediately above the left exhaust pipe. There has been no noticible effect on transponder function.
