being re-radiated by the transmit antenna. The DXE-ARAH series active horizontal antenna
system also grounds the antenna element when power is turned off for protection of the active
devices.
When using transmitting radio systems and RF amplifiers a sequencer such as the DXE-TVSU-1A
Time Variable Sequencer Unit should be used to ensure the correct timing while switching from
receive to transmit, and back to receive.
Features

Sensitive − weak signal sensitivity rivaling full size antennas

Wide Bandwidth – 100 kHz to 30 MHz
 Excellent Strong Signal Handling − outstanding Third Order Intercept of +30 dBm

Reduced Noise − quiet FET followers and exceptional feedline shield isolation

Close Spacing from Transmit Antennas – element grounded at power-off

Long Life − high quality stainless and brass mounting hardware, metal enclosure



DXE-F6 - 75Ω F-6 Style, Direct Bury Coaxial Cable: Full Spool or Custom Cable Assemblies.
Flooded coaxial cable is recommended. CATV F-6 is a high quality 75Ω flooded coaxial cable.
Contact DX Engineering to have custom lengths of CATV F-6 cable manufactured with DXE-SNS6
- Snap-N-Seal 75 ohm Coaxial Connectors installed.

DXE-CPT-659 - Coax Cable Stripper for CATV F-6, RG-6 and RG-59 coaxial cable. DX
Engineering’s economical stripping tool prepares CATV F-6 style coax for connectors in one
operation and includes an extra cutting cartridge.

DXE-SNS6-25 - Watertight Coaxial Connector, Snap-N-Seal for CATV F-6 Cable, 25 pieces
The feedline shield is used as the ground return for the active antenna power, so the feedline
connections must be high quality and weather resistant. For this reason, it is recommended using
Snap-N-Seal type F connectors.

DXE-SNS-CT1 - Compression Tool for Snap-N-Seal 75Ω Coaxial Connectors. The DXE-
SNS6-25 connectors cannot be installed with normal crimping tools or pliers. An installation tool
such as the DXE-SNS-CT1 is essential for proper connector installation.

PTX-82180 - DX Engineering Approved RTV Sealant. Permatex Black RTV Sealant, Non-
Acetic. Avoid using any corrosive sealant which has a vinegar-like smell.

PTX-81343 - Anti-Seize should be used on stainless steel hardware (small amount on threads) to
prevent galling.
