Termination Resistor, 1000 Ohm Non-Inductive for T2FD, BBTD, Rhombic, 1-61 MHz, 600 Watts PEP
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: 1000 ohms (+/- 10%)

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

CW/FT8 (50% duty cycle) in watts: 300

Length (tip to tip) Inches: 14"

Width inches: 3"

Inductance < 20 nH (1-61 MHz)

Internal Resistance Wattage: 200 watts

you can use 2 of the 1000 ohm resistors in parallel to yield 500 ohms total and double the power at 1200 watts. Perfect for high power antennas with 9:1 transformers requiring 500 ohm termination resistance total.

Excellent Install of BBTD by K1FU

Delivery Note (2/15/2023) - we are currently out of stock but will have more in stock around April 1, 2023. You can order now to get in the queue for the next 100 resistors.

12:1 Baluns are useful between 600-650 ohm balanced loads the impedance at the  end of the feed line is 600 ohms (1/2 wavelength feed line), or high impedance feeds for rhombic,  T2FD and traveling wave antennas.

12:1 Ununs are useful between coax and long wires with a load impedance near 600 ohms like a beverage antenna.  Shortwave listener antennas also can benefit with the 12:1 unun and it may provide a better match than 9:1 ununs – this means quieter noise levels and stronger signals so you can hear distance stations easier.
