The new MRF-300 has 3.5 mm jacks. The problem was that their engineers were from oversees, where I guess the standard was 2.5mm for some reason. The engineers fought the sales team for a while about it, but apparently sales won out (and rightly so with all of our complaining). MRF-300 is shipping at the end of this month, I believe. We're looking forward to testing it - the antenna is detatchable, so if there is interference at the headend, you can detatch and move it to a better location.
