May 16, 2019– Comtech Telecommunications Corp. (NASDAQ:CMTL) announced
today that during its third quarter of fiscal 2019, its Tempe,
Arizona-based subsidiary, Comtech EF Data Corp., which is part of
Comtech’s Commercial Solutions segment, received a $1.0 million
equipment order for an Air Traffic Control (“ATC”) communication network
in Latin America.

The order specified NetPerformer™
Satellite Routers
developed by Comtech EF Data Corp.’s subsidiary,
Memotec, which deliver highly reliable, secured communications across
hybrid terrestrial lines, as well as microwave and satellite
transmissions. The NetPerformer platform combines the functionality of a
data router, a multiplexer and a voice gateway in a single device,
enabling users to create converged networks and transport
mission-critical information over satellite or terrestrial links.

The Memotec NetPerformer ensures that Air Traffic Management (“ATM”)
services are prioritized adequately and cost efficiently delivered using
the best available path at any time, thus enabling ATC networks to be
compliant with EUROCAE WG67 ATM standards. The NetPerformer meets
stringent service quality requirements for delay, jitter and packet
loss, and compensates for transmission network delays, enabling Air to
Ground VHF radio communications and radar information to transit
seamlessly across terrestrial or satellite links. It is the only
solution compliant with VHF-AA (“VHF Extended Range”) EUROCAE
specifications. As a voice and VHF over IP gateway solution compliant
with EUROCAE WG67 ED137-B, the platform is a key enabler for the
evolution of ATC services towards all-IP networks.

“We are honored to have been selected to supply equipment for this
mission-critical network,” commented Fred Kornberg, President, and Chief
Executive Officer of Comtech Telecommunications Corp. “Our NetPerformer
