3M Temflex™ 2155 Rubber Splicing Tape

   

Conformable self-fusing rubber electrical insulating tape.  It is designed for low voltage electrical insulating and moisture 
sealing applications.  For outdoor use, it should be protected from UV deterioration with an overwrap of

Highly conformable super stretchy tape for all weather applications.  This tape provides flexibility and easy handling for all 
around performance.  It also combines PVC backing with excellent electrical insulating properties to provide primary 
electrical insulation for splices up to 600V and protective jacketing. Both tape products are available from DX Engineering. 

 
DXE-VMN-1  -  Vertical Antenna Matching Network  

The 

DXE-VMN-1

 Vertical Antenna Matching Network is custom designed for use with base-fed quarter wave resonant vertical 

antenna systems.  In some vertical antenna installations with excellent radial systems, achieving the best SWR on a 
resonant vertical for 80 meters may be difficult without some means of adjusting feedpoint impedance. The 

DXE-

VMN-1

 allows easy adjustment for lowest SWR. The 

DXE-VMN-1

 Vertical Antenna Matching Network will aid in 

tuning a low impedance antenna to the minimum SWR in the customer selected portion of the 80 meter band.  The #12 
AWG coil wire is tin-nickel plated for high power handling, corrosion resistance, ease of soldering and long term 
reliability.

  

As an added benefit, the 

DXE-VMN-1

 will also act as a static bleed for your resonant vertical antenna in 

areas where precipitation or snow static is present. The Vertical Matching Network may be installed between ground 
and the feedpoint of any quarter wave base-fed vertical antenna - including mobile antennas. It 

CANNOT

 be used on 

non-resonant antenna such as a 43 foot vertical.
