Termination Resistor, 500 Ohm Non-Inductive for T2FD, BBTD, Rhombic, 1-61 MHz, 600 Watts
Store/Antenna Products/Complete Antenna Systems/Broadband Terminated Dipoles (T2FD, BBTD)
Product Details

Broadband, Non-Inductive Termination Resistor load used on many terminated antenna types such as T2FD, Broadband Terminated Dipole (BBTD), Rhombics and others

Resistive Value: 500 ohms (+/- 10%)

SSB (25% duty cycle) rating in Watts: 600

CW/FT8 (50% duty cycle) in watts: 400

Length (tip to tip) Inches: 14"

Width inches: 3"

Inductance < 20 nH (1-61 MHz)


Internal Resistance Wattage: 200 watts

If you need more power rating, consider putting two TR-1000-600 resistors in parallel for a total of 1200 watts at 500 ohms.

Mobile RFI kits work two ways: They suppress RFI from on board computers and other sensing/control devices in your vehicle that may cause your radio to be a VICTIM of RFI, and second they suppress RFI generated by your radio as a SOURCE which may affect your on board computers or other devices.  Mobile operations of HF radios (1-30 Mhz) tend to experience more RFI effects than VHF/UHF mobile stations.  If you have both HF and VHF installations in your vehicles, you may need both kits.

To address separate solutions we have developed two separate RFI kits: one for HF (1.8-300 MHz) mobile installations and another for VHF/UHF (30-1000 MHz) mobile installations.  Each kit uses the appropriate ferrite mix for the frequency range desired.
