DXE-CPT-659 - Coax Cable Stripper for CATV F-6, RG-6 and RG-59 coax 

Prepares CATV F-6, RG-6 and RG-59 coax cable for the installation of an "F" type connector.  

 

One-step cutting motion  

 

Precision cut  

 

No nicks or scratches to conductor  

 

Includes 1 replacement blade 

 

 
 
DXE-SNS6-25 - Watertight Coax Connector, Snap-N-Seal for CATV F-6 Cable, 25 pieces 

 

Snap-N-Seal is an environmentally sealed CATV F coax connector system for harsh environments. The connectors have a unique, 
360 degree radial compression system that offers the signal leakage protection required for high performance receive systems.  

 

Quad sealed system prevents moisture from migrating into the connection  

 

360 degree radial compression provides superior RF integrity (-95 dB typical, 60% bonded foil cable)  

 

Easy cable preparation  

 

Connector to cable retention of 40 lbs minimum  

 

Superb impedance match to 1 GHz  

 

Manufactured of high quality 360 brass, cadmium plated with yellow chromate coating for maximum corrosion resistance  

 

UV-resistant plastic and O-rings provide a reliable environmentally sealed connector 

An installation tool, such as the 

DXE-SNS-CT1

, is required to install the connectors. Normal crimping tools or pliers will not work. 

 
 
 
DXE-SNS-CT1 - Compression Tool for Snap-N-Seal 75 Ω Coax Connectors 

 

Ratchet compression tool for installing Snap-N-Seal 75 Ω Coax connectors. Ordinary pliers will not install these 
connectors properly.  
 
 

 
COM-CW4 - Cable, 4 Conductor, Sold per Foot 

 

A high quality, PVC jacketed 4-wire control cable, COM-CW4 consists of 4 #20 AWG conductors. It may be 
used in a multitude of control cable applications, such as remote switching and antenna rotators. 
  
Sold by the foot - order the length you need. 

 
 
 
DXE-ARAV3-4P - Receive Antenna Active Vertical w/Relay Pkg. of 4  

The 

DXE-ARAV3-4P

 Active Receive Antenna array package contains 4 of the 

DXE-ARAV3-1P 

Active Receive Antennas. This 

package is intended for use with the 

DXE-RFS-3P

 Receive Four-Square system to build a Four-Square Receiving Array. The FVI-1 

Feedline Voltage Injectors are not included as the RFS-3 has provision for powering the 
active antennas. 
The ARAV3-4P Vertical Array System package Includes:  

 

Four Active Antenna Verticals, for use with the DX Engineering 

DXE-RFS-3P

 

Receive Four Square system. 

DX Engineering’s Active Receive Antenna system offers excellent receiving performance 
from 100 kHz to 30 MHz using a whip antenna element 102 in. long. DX Engineering’s 
unique design makes it vastly superior to traditional active antennas in both strong signal 
handling and feedline decoupling. You get significantly better weak signal reception due 
to lower spurious signal interference and reduced noise. This antenna system is ideal for Amateur Radio or Shortwave Listening.  
 
The 

ARAV3-4P

 active antenna grounds the antenna element when power is turned off. This active antenna is used in installations 

with spacing from transmit antennas less than 1/2 wavelength but more than 1/10 wavelength (on the lowest frequency). Sites with no 
room for proper spacing should use the ARAV3-4P, which can be installed in close proximity to transmitting antennas (1/10-
wavelength of the lowest transmitting frequency), provided the unit is powered off at least 5 ms before transmitting. A sequencer 
such as th

DXE-TVSU-1B

 should be used to ensure the correct transmit to receive switching. The 

DXE-NCC-1 Noise/Phase 

Controller 

can provide the power for the active antenna and the proper transmit power-off sequencing.
