DXE-F6 - 75 Ω F-6 Style, Direct Bury Coaxial Cable: Full Spool or Cu stom Cable Assemblies
DX Engineering recommends using a high quality 75 Ω “flooded” F6 type coaxial cable. Flooded style cables
have the distinct advantage of automatically sealing small accidental cuts or lacerations of the jacket. Flooding
also prevents shield contamination and can be direct-buried. This low-loss cable features dual shields and an
85% Velocity Factor.
Custom cable assemblies are available, Call DX Engineering for details.
DXE-SNS6 Snap-N-Seal connectors are recommended for use with this coaxial cable to ensure a high quality
and weather resistant feedline connection. The proper tool DXE-SNS-CT1 must be used to install these connectors.
DXE-CPT-659 - Coax Cable Stripper for CATV F-6, RG-6 and RG-59 coaxial cable
Coax Cable Stripper for CATV F-6, RG-6 and RG-59 coaxial cable.
Includes 1 Replacement Blade - DXE-CPT-659
Prepares CATV F-6, RG-6 and RG-59 coaxial cable for the installation of "F" type connectors - One-step cutting
motion

Precision cut

No nicks or scratches to conductor
DXE-SNS6-25 - Watertight Coaxial Connector, Snap-N-Seal for CATV F-6 Cable, 25 pieces
Snap-N-Seal is an environmentally sealed CATV F coaxial 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 (-95dB 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 Coaxial Connectors
Ratchet compression tool for installing DXE-SNS6 Snap-N-Seal coaxial connectors. Ordinary pliers will not install
these connectors properly.
DXE-TVSU-1A - Time Variable Sequencer Unit
The DX Engineering TVSU-1A Time Variable Sequencer Unit is a microprocessor-based transmit / receive control-signal delay
unit. It provides 0-30 ms of delay, programmable in 2 ms increments, to as many as five outputs tied to the CW keying or push-to-
talk (PTT) lines.
By controlling the receive-to-transmit (and back) timing of linear amplifiers, preamplifiers, and other sensitive equipment, damage
caused by improper switching can be eliminated.
This sequencer improves CW performance by eliminating annoying leading edge chopping or truncating of Morse characters. This is
especially important in contests or pileups where sending accuracy is critical.
The TVSU can also control external devices such as preamps, active antennas, or external relays that need
to have power removed during transmit. Separate power-in and power-out jacks on the front
panel are used to control external power in this type of application. Two 2.1mm power plugs and two
3.5mm stereo plugs are provided.
Benefits

Control timing of PTT turn-on, hang delay of PTT, amplifier hang delay, external antenna relay hang delay and turn-on delay of
auxiliary output

Dip switch settable delays of 0-30 milliseconds in 2 millisecond steps

Side tone generator that follows input of keyer or hand key not transmitter

Side tone pitch can be programmed from 300 to 1000 Hz in 50 Hz steps, front panel headphone jack with adjustable volume

Supports CW full break in

Can control external power to our Active Receive Antennas and permit operation in closer proximity to transmit antennas
