It has a wide frequency range from 0.1 to 230 MHz, allowing users to analyze and tune various types of antennas. The analyzer is equipped with a built-in SWR meter, providing accurate measurements of standing wave ratio and impedance. It also features a large LCD display that shows important information such as frequency, SWR, and impedance. The Mfj-269c-PRO is portable and easy to use, making it a valuable tool for both experienced and novice radio operators. It can test and tune stubs and coax lines, manually determine velocity factors and impedances of transmission lines, and adjust and test RF matching networks and RF amplifiers without applying power. It has an easy-to-read LCD logarithmic SWR bar graph and SWR meter for quick tuning. It is fully portable and can be taken anywhere, including remote sites, up towers, and on DX peditions. The analyzer has a built-in “N-type” connector and includes a free N-to-SO-239 adaptor. It can be powered by 10 AA Ni-MH or Ni-Cad or alkaline batteries (not included) or 110-240 VAC with an optional MFJ-1312D. The Mfj-269c-PRO is compact, measuring 4W x 2D x 6 3/4H inches, and provides maritime and 600-meter coverage
