DXE-WP-102  -  102 inch Stainless Steel Whip

 

This 102'' whip antenna is made from the finest 17-7 ph tapered stainless steel which resists bending and kinking. This material is so 
tough it can be bent 180 degrees and will spring back to its original shape. Dissipation tip to reduce unwanted static buildup. Fits all 
3/8 x 24 threaded mounts.  
 

 

Can be bent 180 degrees and will spring back to its original shape  

 

Resist bending and kinking  

 

Excellent for all off-road terrain 
 

 

DXE-CAVS-1P - V-Bolt Saddle Clamp, 1/2 in. to 1-3/4 in. OD Applications

 

This V-Clamp is made in one size that fits tubing from 1/2 to 1-3/4'' OD as used in antenna construction. The supplied V-bolt is long 
enough to attach tubing to thick plates and is made with anti-corrosive properties. The cast rippled surface of the saddle will clamp 
the tubing securely to a flat surface; however, for high-torque applications please use our standard U-Bolt Saddle Clamps.  

 

Used to clamp 1/2 to 1-3/4'' (OD) tubing  

 

Designed for attachments that don't require resistance to torque  

 

V-bolt made from high-strength 18-8* stainless steel  

 

V-saddle cast from 535 aluminum with rippled surface 

The use of an Anti-Seize compound is HIGHLY recommended to achieve proper torque and prevent galling.  
 
 
 
 

JTL-12555  Jet-Lube

 SS-30 Pure Copper Anti-Seize  

Jet-Lube

 SS-30 Pure Copper Anti-Seize is the top choice of engineers and technicians in government, industry and leading Amateur 

Radio contest stations, for protecting mechanical assemblies of aluminum tubing, general hardware and copper grounding 
systems. On bonded metal surfaces Jet-Lube

 SS-30 assures electrical and RF conductivity while preventing oxidation 

and corrosion. Surpassing the capabilities of other aluminum anti-oxidants, the wide temperature range of Jet-Lube

 SS-

30 prevents long-term drying and caking, and allows easy disassembly and effortless cleaning of parts. An 
environmentally preferred thread lubricant and conductive termination compound, Jet-Lube

 SS-30 helps keep your 

equipment in serviceable condition. It contains a high concentration of copper flakes, a requirement for heavy loads or 
compression; controlled frictional characteristics allow the surfaces of nuts and bolts to be tightened to their design torque 
specifications. This anti-seize product assures full hydraulic efficiency by allowing the metal surfaces to slide over each 
other without damaging metal-to-metal contact. Jet-Lube

 SS-30 is also designed to work as a similar and dissimilar 

component between two metal surfaces to prevent seizing and galvanic action. The SS-30 compound formula improves 
conductivity and ground continuity - and will not melt in high temperatures.  
  Jet-Lube

 SS-30 Pure Copper Anti-Seize Features include: 

* Meets MIL-PRF-907E spec 
* K-factor: 0.13 
* Service rating: -65 degrees F (-54 degrees C) to 1800 degrees F (820 degrees C) 
* SS-30 Resistivity (ohm-CM x 108) 5
