2 comms...

Jimzim · #1 07-12-2012, 05:13 AM

I'm currently at the panel planning statge. I plan on 2 com radios, so I need 2 seperate antennas, correct?? They cannot share 1? Also, does anyone have experience with mounting the Skyview ADAHRS in a 7? I'm not sure what might be a good spot...
Thanks, Jim

As for the comm's, yes you will need 2 seperate antennas.

Jim, a good spot that's often used and away from ferrite interference is on a tray, suspended from the upper framework, just behind the baggage area.

It's also easily accessible by simply removing just the upper half of the baggage wall.

Best,

Best,

Unless of course you have a slider and want to have it open when you power-up. I am putting mine on the aft side of F-607 just above the floor.

This worked for me...

The shelf depicted above is very common as is the aft deck, but I would recommend greatly simplifying the pitot/static connections and hookups. There are extra joints in that particular setup as shown for leaks to eventually develop. Not flaming the install, just saying it could be simper from a plumbing perspecting - and simpler is almost always better when it comes to pitot/static plumbing.

And yes, the other folks are right...one antenna for each comm radio.

Cheers,
Stein

Make sure to put the ADAHRS at least one bulkhead aft of the baggage compartment. That way you won't have to worry about what is in the baggage compartment.

You can check out this thread for pictures of my install.

One builder I spoke to said he was putting his in the wing, which is still within the box called out in the SkyView manual.

I'll have nightmares tonight from just looking at it.

On the other hand, I make a living fixing leaks... so it's not all bad

Thanks very much for all the feedback! I'll have to think it through a bit further, but now I have some good options...Can't wait to get over the hump with all the avionics/wiring and get back to the more mechanical side of things. Much more in my comfort zone there, but I guess that's why it's both "recreational and educational!!
Thanks, Jim

Stein, I'm not real happy with the ADAHRS plumbing either. One of the problems was having to connect the two units in parallel using the bulky connectors you see in the picture. If I had it to do over again knowing what I know now, it would probably be different. Having already passed the pitot/static check, I'll leave well enough alone for now, but I'd like to talk to you at some point to get your recommendations for improvement before my next pitot/static check.
