A:AnswerHi - I am sorry but I do not know of any other antenna that would fit - I only am using the included antenna lead and have no issue - I get great reception - Perhaps your location is part of the issue - I am sorry I could not offer more assistance -
A:AnswerI'm not positive, but I think so. I know my car bluetooth works when my cell phone is in the house. So I think the bluetooth in all 4 units should be picked up. Hope that helps.
A:AnswerI am using an FM radio transmitter from my main stereo that is connected to the FM transmitter. There are a few on the market. Overall it works pretty well when I tune in to the frequency that works the best. I have at least 4 FM receivers that get the signal.
A:AnswerI think you could use a Bluetooth transmitter (available on bestbuy) plugged into the headphone jack to stream to a Bluetooth speaker. I'm not sure, but I think the system speakers will mute when anything is plugged into the headphone jack.
A:AnswerAny F connector (round with flush pin that pushes onto the round connector in back) will also work, not just the odd shaped connector that is supplied (though this one was sufficient for my reception area to receive classical WRR in Dallas, really the only station I was interested in). If BB doesn’t carry one, the usual online suspects will offer ones of greater length, though even those can be problematic depending on your distance from transmission towers. AM isn’t an issue since this unit doesn’t provide an AM band.

A:AnswerI do not use the clock function on my unit, but if you turn it off by the power switch on the back, that may be the problem. If you turn it off from the remote, it doesn't shut off the power completely. It goes into a 'sleep' mode, and I would think your clock would stay displayed. I hope this helps.
A:Answerno, this unit has two built-in speakers on the front and a (small) subwoofer underneath that provides decent sound. You can't actually connect this to external speakers, even if you wanted too.
