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.

Excellent BBTD Install info by K1FU

OCF antennas are very convenient as they will allow multiple bands of operation with a simple wire antenna which is fed off center with a 4:1 OCF Current balun with built in feed line choke,
