Amphenol Procom
The Distributed Antenna Systems (DAS) function is to enhance the performance of a wireless network coverage of a specific area. DAS is a network of antennas which are all connected to the same source. The DAS solution is more efficient than having a large single antenna to cover an area and that’s why it is highly suited for in-buildings service and a restricted outdoor area. Amphenol Procom offers a wide range of both indoor antennas and passive devices, especially for Public Safety applications.

Becker Nachrichtentechnik GmbH
Modern receivers for broadcast have a large number of antenna inputs for the different radio bands. The devices of the FDMX series can be used to supply the antenna inputs with RF signals. The devices of the FDMX series splits a sum signal in frequency division multiplex into the individual broadcast bands and the L1 satellite navigation band (GNSS). Additionally, DC loads are provided for each antenna input to simulate active antennas. The presence of remote power supply is indicated by an LED on the units.

Doppler Systems Inc.
This assembly contains three sets of antennas, three RF summers, an antenna switch, a GPS and (optionally) a flux gate compass. The pod mounts to the roof with nylon straps, although it is recommended that it be bolted down for more permanent applications. Although this antenna is not stocked, we can provide them on relatively short notice. No minimums apply.

RAM-34 -
Array Solutions
The RAM-34 is a complete pre-amplifier system designed primarily for the low bands 160M thru 40M. It has inputs for four receive antennas and internal 3-pole bandpass filters for 160M, 80M and 40M. In addition to the pre-amplifier, it has a step attenuator that togetherwith the amplifier stage provides gains from -20 dB to +20 dB in 5 dB steps. This allows equalizing the signal levels between the antenna inputs. Gain settings are memorized for each antenna on each band. Different types of receive antennas have different signal levels and the gain memories eliminate the need to adjust the receiver or pre-amplifier when switching between the antennas.

Type 2-MQ -
National RF, Inc
The Type 2-MQ Portaquad is a high-gain, full size 2-meter quad antenna designed for portable operations. The mechanical design allows it to fold for stowage or transportation in a container. The container also acts as the antenna’s support base when the antenna is erected. After familiarity with the device is achieved, the antenna may be erected or collapsed in approximately one minute.

Antenna Research Associates
Vehicular and Handheld antennas are available for communication, surveillance, signal DF, network repeaters and RF Jamming applications. A single omni or high gain directional ARA antenna may cover all cellular and/or Tetra communication bands and are compatible with all network technologies (GSM, CDMA, etc.). These wideband antennas replace the need for several single band antennas and are ideal for vehicular installations as well as handheld radio mounted applications. Permanent installations, quick deploy magnetic mounts or convenient pistol grips for radio location are available.

Spirent Federal Systems
The Spirent CRPA Test System is a development of Spirent’s GSS9000 Series platform for testing Controlled Reception Pattern Antenna (CRPA) systems with a separate RF output per antenna element. The CRPA Test System generates both GNSS and interference signals. Users can control multiple antenna elements. Null-steering and space/time adaptive CRPA testing are both supported by this comprehensive wavefront approach.

SX-SDMAC2 -
Silex Technology
The SX-SDMAC2 is a dual band IEEE802.11 a/b/g/n/ac WLAN and Bluetooth 5.0 BR/EDR/LE (Class1) module based on Qualcomm QCA9379-3 chipset. It supports 2x2 antenna configuration for applications that require higher performance. Silex has separated the Bluetooth antenna from the Wi-Fi by creating a third antenna port, allowing concurrent operation of Wi-Fi and Bluetooth further optimizing the Wi-Fi and Bluetooth performance.
