Antenna wire: amount
I assume that I should probably use the following cable wire for the comm and gps:
RG-400 M17/128 Rf Double Shield Coaxial Cable
How much would I need? A rough guess. 30 ft?
thanks
ken

Get double plus 25% of what you need .. so when you cut it 1 inch too short you don't have to pay shipping again
Seriously ... don't forget enough to learn how to install the connectors, order extra connectors to train with, and leave enough for service loops in case you have to re-terminate later to troubleshoot.

Depends on what you will use.
At least one com-com antenna under the seats
A transponder antenna in the back
Probably to an IFR GPS antenna on top behind the canopy
a com2?
will you make you own EFIS GPS antenna or buy an antenna with cable
My com antenna cable, IFR GPS Antenna and Transponder antenna cables are probably closer to 50-60 ft in total

Just to add to what Control has suggested, it also depends on where those antenna will be located.
As a reference, my GPS (two of them) antennas are in the wingtip as well as my VOR. The TXPDR and remote radio are behind the baggage compartment and I believe I bought 100' and used majority of it.

well, the transponder antenna cable comes with the empennage kit. It is interesting that that does come with the kit while the comms do not. I have a gtx 45, which has one antenna for both the ADS-B and the transponder. ALso, I think that I have a gps antenna for the EFIS that came with the panel. I wil have to verify.
The VOR antenna will come with a wire. I plan to go with the whiskers in the vertical stabilizer and I can get antenna with the cable.
So it is just the 2 comms under the seat and the GPS on the top of the empennage. Steinair suggested 60'. I was thinking that was overkill.

Does a VOR antenna use coax cable? like:
RAMI AV-532L VOR ANTENNA WITH CABLE
the picture on ACS with cable shows wire ends that don't look like cable terminal.

I bought 60' and used most of it. My VOR antenna (Archer in wingtip) did not come with wire.

I have the same transponder and used the forward mounting antenna position under the seats. I recall the maximum length of coax is supposed to be about 8 feet. The rear antenna position I understand was for an ADSB IN antenna which is now handled by the single forward one. So I removed the coax to the tail and used for one of the coms. The second Com and IFR GPS on the turtle deck took about 25 feet which I purchased.
