VHF Antenna
 
In Section 28 of the lower fuselage it shows two mounting plate doublers for antennas in Fuselage flooring. I can only assume this is for the VHF com1 com2 antennas. They have mounting and cable connection holes. Great. The only problem is that I now need to drill out and mount my antenna with a different four bolt mounting system. They obviously made these areas for an antenna that I am not using. Can anyone tell me what antenna fits the stock two screw mounting system?

I used the RAMI antennas, they fit without any modification:

Van?s has those same Rami AV-17 COM antennas for a lower price. I?ve searched around and as far as I can tell it?s the best price available.

My personal preference is straight antennas whenever possible (which is what I use on my RV7) due to the lower VSWR.

There is also Delta Pop straight and bent.

routing
 
Hi all,

When using these antenna locations under the control column cover, how did you route your rg400?

My stick grips have too many wires and basically fill up the small bushings on the lower front side of the ribs.

Is there another way you ran them through to get to the center tunnel?

thanks
Mark

I used the bent ones from Vans. Work perfectly well. Picked up ATIS at 70 miles, 7500 feet on a trip recently.

Turner - I wasn't asking about the antennas, but the cable The rg400 cable, how was that routed to the center tunnel?

thanks
Mark

I ran my comm RG-400 thru the center tunnel, then outboard running parallel to the fuel lines thru one of the 2 holes in the fuel line brackets. Bare cable fits perfectly, then added the BNC connectors afterwards.

What are the pros/cons of bent versus straight antenna?
Sorry for the thread drift.
