DX Engineering Hot Rodz® Antenna Capacity Hats
The patented* DX Engineering Hot Rodz® antenna capacity hat systems are designed to increase the efficiency and gain of single-band vertical antennas, such as those from Hustler and Pro Am. They can even shorten the height of the antenna by eliminating the need for a whip.
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.
There are two different DX Enginering Hot Rodz® Capacity Hat systems available:
DXE-HR-1P - DX Engineering Hot Rodz® Adjustable Antenna Capacity Hat

DX Engineering Hot Rodz® Capacity Hat Rods are used at the top of a vertical to increase the efficiency and gain of your antennas. They can also be used on mobile and portable verticals with the Hot Rodz® Hubs by experienced antenna practitioners. DX Engineering Hot Rodz® Capacity Hat Rods are longer and allow greater range of adjustment on your capacity hat systems.
