ACK E-04 Whip Antenna
This was a replacement for the original that the plastic totally fractured. I live in the northwest, plane always hangared, not left in the sun very often. I think the plastic base was of a poor quality. I also had a failure on my revious ACK ELT. I would buy a different brand next time.

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.
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.
To comply with the TSO installation instructions the external antenna will require replacement as well.
Approx 21.5 inches
Yes it uses a standard bnc connector and the nut is standard/typical.
Approx 20.5 inches.
Yes, as the new ELTs transmit both 121.5 and 406. however typically ELT antennas should be for the brand ELT that is installed. It is not recommended to use an ACK E-04 antenna for another brand ELT.
