Product Information
  • Overview
DX Engineering Hot Rodz™ Antenna Capacity Hat systems are designed to increase the efficiency and gain of single-band mobile vertical antennas, such as those from Hustler and Pro Am, or on mobile "screwdriver-type" adjustable frequency antennas. They can even shorten the height of the antenna by eliminating the need for a whip while maintaining the same or a lower resonant frequency. The DX Engineering Hot Rodz™ antenna capacity hats can also be used on the Hustler 4, 5, and 6-BTV series antennas by experienced antenna practitioners. 

When an antenna is shortened from its naturally resonant length, the feedpoint becomes capacitive. To offset the additional capacitance, it is common to add inductance in the form of a loading coil to restore the resonance. However, the additional inductor increases the resistance, which increases the loss in the antenna. 

DX Engineering Hot Rodz™ Antenna Capacity Hats solve the problem by using a capacity hat--a series of horizontal rods that counters the effects of shortened vertical antennas.

DX Engineering Hot Rodz™ Antenna Capacity Hats Systems include:

* Precision-machined 6061 T6 hub 
* Stainless steel set screws 
* 18 pre-cut stainless steel rods: 
* 3 sets of 6 in. stainless steel rods
* 3 sets of 12 in. stainless steel rods 
* 3 sets of 24 in. stainless steel rods 
* 18 plastic safety tips 
* Aluminum hub
