Q: What is the height of the Comant CI 122 antenna?
The total height is 18.5 inches long, as the CI-122 is a bottom mount antenna it is bent.
Q: How far does the Comant CI-122 hang down below the mounting surface?
Per the manufacture it is 8.75" from the base of the antenna to the bend.
Q: Does this antenna come with coax cable and connectors?
No, this is the price for the antenna only. Connectors and BNC connectors are sold separate.
Q: What screws are used to mount the antenna? Do they have to be any special material or just standard AN hardware with the appropriate screw head to fit into the countersink body of the antenna.
For part number 11-17922 the length of the screw depends on the mounting location. The mounting holes are .173 diameter and countersunk AN hardware is recommended.
Q: Does the CI-122 or the CI-121 require a metal aircraft frame to act as a ground plane or can these 2 antennae models be used on a non conducting surface like fiberglass? Does the type of aircraft material change the VSWR from the specifications?
The CI-122 (11-17922) does require a ground plane if mounted on a fiberglass airplane. The height of the antenna is the required diameter of the ground plane. Aircraft material does not change the VSWR of the antenna.
Q: What type coax is used with the CI 122 antenna?
On certified installations, we recommend using either RG400 or RG142.
Q: How many mounting screws for this antenna?
This has a footprint for four (4) holes.
