MFJ 259B

1.8-170 MHz SWR Analyzer

Covers 1.8-170 MHz, two-line LCD screen and side-by-side meters. You can ensure your antenna system is giving you top performance by using an MFJ SWR Analyzer. They're completely portable test stations, featuring a Frequency Counter, RF signal generator, SWR Analyzer, RF Resistance and Reactance Analyzer, Coax Analyzer, Capacitance/Inductance Meter and more. You can take it to the antenna and just one reading will allow you to make quick tuning adjustments on the spot. Simple Operation - just connect the feed line, set the bandswitch and tune the dial. All information is clearly displayed on the large, easy-to-read, two-line LCD screen and side-by-side meters on the 259B/269. When tuning transmission lines or making up phasing harnesses for stacking antennas, you can quickly determine exact 1/4 or 1/2 wavelengths. Determine the velocity factor, coax cable loss, length of coax and distance to a short or open in coaxial cable. Read SWR, return loss and reflection coefficient at any frequency simultaneously, or inductance and capacitance at RF frequencies at a glance. All except the 266* are powered by (10) AA Alkaline or Ni-Cad/Ni-MH rechargeable internal batteries (not included), or 110V with the MFJ-1312D adapter. There is a built-in charger circuit that requires external 12V DC or the 1312D adapter. The 249B and 259B have an SO-239 antenna connector, the 266 and 269 has a type-N female and is supplied with a type-N to SO-239 adapter. All metal cabinet. Dim: 4"w x 6-3/4"h x 2"d.
