After my review of my MFJ-207 Peter VK2TPM offered me his MFJ-269 to play with for comparison. Naturally I jumped at the chance. The MFJ-269 is the fully-featured descendent of the earlier and simpler antenna bridges like the MFJ-207. The manual can be found on MFJ's website.

The device is microprocessor based with an LCD interface and two main control buttons "Gate" and "Mode". There is also a Frequency band switch, a reduction geared tuning capacitor, power and UHF mode switches. Two analogue meters display SWR and impedance magnitude continuously, offering a trending display which is more user-friendly than the figures on the LCD display. In UHF mode there is a "bargraph" of sorts on the 2nd line of the LCD for trending SWR.

The unit tunes about 1.76 MHz to 172.7 MHz in six overlapping bands. There is also a "UHF" switch that triples the oscillator in the 114-170 band giving 415-470 MHz coverage the edges of which are enforced in software, the display telling you to increase or decrease frequency until within that band. UHF supports only loss and SWR features, not reactive measurements - likely because bridge performance issues at UHF would have required extensive calibrations to have any hope of accuracy.
