ComDat® FAQ’s
ComDat® FAQ’s
What is ComDat?
ComDat stands for Communications / Data, and represents a new series of antennas made exclusively by Comant. These antennas acquire data for
some of the newest aviation systems begin offered, such as Orbcomm, Iridium, WSI, XM Satellite Radio, as well as GPS and VHF.
How are ComDat antennas different?
ComDat antennas combine many of these new antenna requirements into one, reducing the number of antennas an aircraft requires in order to utilize
services such as Orbcomm or GPS. Plus, most ComDat antennas are packaged in Comant's new 248/2480 radome shell, offering a sleek, low drag
package that is as tough as it is good looking.
How are ComDat antennas the same?
ComDat antennas share Comant's standard VHF (CI 121) and teardrop GPS (CI 405 series) footprints, making them virtual drop-ins for
A installation ease.
v
i
o
Why is the concept of combining antennas important?
n
i With the proliferation of new systems like Orbcomm or WSI, etc., there is simply not enough room on aircraft (especially smaller GA aircraft) to
c
s accommodate more antennas. Airframe builders like Cessna, Piper and Cirrus must offer these new systems to their customers, and are demanding

& that the required antennas be combined with other systems in order to save space and reduce drag.

A
c This sounds simple. Why hasn't it been done before?
c Various antenna frequencies can interfere with each other. For example, VHF can interfere with GPS, rendering GPS useless. That's why separate
e
s VHF and GPS antennas must be at least three feet apart when mounted on an aircraft. In the case of the combined GPS/VHF ComDat, Comant has
s patented an integrated third-order notch filter, removing the harmful VHF harmonics that interfere with GPS reception.
o
r
i
e What makes the CI 248-5 VHF a ComDat antenna? How is it different from other VHF antennas?
s
The ComDat CI 248-5 VHF antenna contains an integrated GPS notch filter. This eliminates the need for this stand-alone VHF to be three feet away
from a GPS antenna, making more room available on the airframe. For example, single engine Cessna aircraft have both VHF antennas, and the GPS
antenna on the wing above the cockpit. Installing a VHF/GPS combination and a CI 248-5 in this area will eliminate the need for in-line notch filters
C on the coax.
o
m How does the VHF/GPS/Orbcomm ComDat work? Does it have three connectors?
a Comant has worked closely with Avidyne in the development of these models. As with other combination ComDat antennas, this version has just two
n connectors. Comant developed a wide-band VHF antenna that operates over the VHF/Orbcomm frequencies. Avidyne developed a specialized switch
t that allows VHF communications (Com 2 suggested) when required, and Orbcomm transmit/receive when activated.
What else is new in the ComDat line?
Comant has developed a 40dB amplifier that will work with Chelton Flight Systems, Trimble, and FreeFlight. It's available as a stand-alone 405 Series
or in combination with VHF and/or Orbcomm. We have also developed a 17dB amplifier for Garmin, and FIS antenna for Honeywell's KDR510, and
Iridium antennas.
Can we get WSI or XM antennas from Comant?
Although manufactured by Comant, currently these antennas are available exclusively from their designated suppliers.
Are ComDat GPS antennas approved for Category 1 NPA's, or ILS?
ComDat antennas are TSO'd to C129a or C144. Comant is working closely with Honeywell and Garmin to assure that ComDat antennas are approved
and listed in installation manuals for their GPS systems. In almost every case, the FAA currently allows ComDat antenna installations by citing
Advisory Circular 20-41A for the substitution of TSO equipment for functionally similar TSO approved equipment.
