MFJ-263 uses a specially designed metal-film non-inductive terminating resistor to cover a very wide frequency range from DC to 3 GHz.

It gives an incredibly low and flat SWR across the entire spectrum. Handles 300 Watts for 10 seconds and 125 Watts continuously.

An N Teflon(R) insulated connector is used to insure minimum SWR. The custom heavy-duty heatsink spans the entire length of the cabinet. Strong, aluminum
construction.
