Q: Can this antenna be mounted underside on the belly of an aircraft with metal airframe?

The install manual states that the antenna is to be mounted on top of the aircraft +-35 degrees of vertical when the aircraft is in normal flight attitude.

Q: What is the length of this antenna and what size ground plane would it require?

The supplemental ground plane must have a minimum diameter of 24" however 48 will provide maximum power at 121.5 MHz and is highly recommended. This antenna is 20.625" long.

Q: I have an AK-451 that Im looking at replacing with the ACK-04. Can I reuse the external antenna from the AK unit or would it need to be replaced with the ACK whip antenna?

To comply with the TSO installation instructions the external antenna will require replacement as well.

Q: What is the overall length of the ACK whip antenna?

Approx 21.5 inches

Q: Does this take standard BNC connector? Is the nut securing the antenna to the fuselage pretty much standard/typical?
