Antenna Switch
SixPak
-
The SixPak has two components: a relay matrix and a control box, there are several options for the controller.The relay matrix allows the selection of any 6 antennas by 2 radios or feedlines. Its lockout circuitry prevents both radios from selecting the same antenna. (The 6x1 type of SixPak is now replaced by our RatPak remote 6 way antenna switch.)The usual set-up has one SixPak dual rotary control box, which is manually operated from the radios positions. The control box for the 6x2 contains two rotary switches and 12 LEDs, so the operator can see which antennas are selected.

Cassegrain Antennas
-
In telecommunications and radar, a Cassegrain antenna is a parabolic antenna in which the feed antenna is mounted at or behind the surface of the concave main parabolic reflector dish and is aimed at a smaller convex secondary reflector suspended in front of the primary reflector. The beam of radio waves from the feed illuminates the secondary reflector, which reflects it back to the main reflector dish, which reflects it forward again to form the desired beam. The Cassegrain design is widely used in parabolic antennas, particularly in large antennas such as those in satellite ground stations, radio telescopes, and communication satellites.

Probe Antennas
-
Probe antennas are offered as both standard and custom models with a rectangular waveguide interface. Probe antennas can only support linear polarization. These antennas are often used to measure the gain of other antennas by comparing the signal levels of the probe antenna and antenna under testing. The standard models operate across the full waveguide band and offer 6.5 dB nominal gain and 115 and 60 degrees half power beamwidth at center frequency. The below standard offering covers the frequency range of 8.2 to 170 GHz.

FLAT Antennas
-
CTG recently developed a new paradigm in linearly-polarized antennas called the Flat Lens Antenna Technology or ‘FLAT’. These antennas have directivities similar to conventional dual-ridge antennas, but in a much lighter and “flatter” package. They can be used as a direct replacement for conventional horns for a wide variety of applications. They are made using composites technology so are also rugged and are ideal for both indoor and out-door applications.

Biconical Antennas
-
For many years most standards called for the use of a half-wave dipole antenna set for frequencies above 80 MHz. However, to reduce test time, broadband antennas such as the biconical antenna and log periodic antennas began to be accepted. Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. A.H. Systems'' 7 models of Biconical Antennas operate efficiently over the frequency range of 20 MHz to 18 GHz. Suitable for FCC, MIL-STD, VDE, TEMPEST, and immunity testing, each Biconical antenna will provide reliable, repeatable measurements.
