Is this length of coax run a problem?

Probably not. Most aircraft GPS receivers use active antennas, i.e. they have a preamp in the antenna to overcome the loss in the coax. -- Brian Lloyd 6501 Red Hook Plaza brianl@lloyd.com Suite 201 http://www.lloyd.com St. Thomas, VI 00802 +1.340.998.9447 (voice) +1.360.838.9669 (fax) There is a time to laud one's country and a time to protest.

But I'm just wondering where you are going to put the comm antenna. You really don't want it anywhere near the GPS antenna.
