[MTCB Android Head Units Q&A] typos1:
I ve got the diversity tuner from Klyde.

Was easy to install (inside the unit).

Where I live the only place I can get a DVB-T signal with the signal tuner DVB-T module was in the front room, with the supplied non amplified antenna hanging out the window, like this, I can get 6 channels but there is often interference and signal break up.

With the diversity DVB-T module and 2 non amplified antennas (in a room where I got no reception at all with the single tuner module) I got all tv and radio channels with only occasional signal loss/break up, this is a massive improvement !

I havent tried it in the car with 2 amplified antennas connected yet, but it does look promising.

Unfortunately, the interface is the same as the single tuner DVB-T module (with the blue and yellow menus as seen previously in this thread), ie, very cheap looking and about 10 years old. Even though, for instance, the radio app is not an Android app, its been made to look like one, same with the DVD app etc, effort has been made to integrate everything, NO effort has been made to integrate the DVB-T tuner GUI, so it looks out of place.

To make matters even worse, it seems that the connection used is low quality like composite video or something - the picture is not that good and the outlines of the onscreen menus is very very fuzzy, its totally at odds with the rest of the unit, which is basically cos this is a 10 year old DVB-T unit modified (not very well - you often have to touch the onscreen buttons twice) to work with touchscreens.

The module is attached to the board by several very large looking pins, there is no way of determining what format the connection is, but its deffo NOT HDMI it must be composite or something because of the quality.

I ve been doing some reading up about getting a better signal. It seems that you can use a diplexer or combiner to join 2 or more antennas together, but just wiring them together could actually make the signal worse as it may cause Doppler shift and interference. I read that using 4 antennas is best as its more likely that at least one will be facing the transmitter. I read that mounting some horizontal and some vertical is good. And apparently experimenting with antenna location is very important. I ve read before that the higher the antenna is mounted on the car, the better, but I ve also read that several manufacturers including BMW, put 2 antennas in the bumper :eek: - - basically, spend hours experimenting !!

I ve searched and searched but I cant find any diversity DVB-T tuners for Android. And I ve searched for a box that could take 2 antenna signals and combine them into 1 good signal to convert a single tuner to a diversity tuner, but the only thing I came up with was diplexers/combiners and a lot appear to be made to combine digital tv and sat or radio signals (ie combine signals from sources that use different frequency ranges), I found a some that can combine 2 signals of the same frequency ranges into 1 like this:

which may work as its supposed to operate from 5 Mhz to 1Ghz on both in/outputs. But I also read quite a bit that said cheap ones like this that are supposed to split AND combine are ****e. Mind you, its very cheap so it might be worth trying it with 2 antennas on a single tuner box.

I also looked for a diversity RTL2832U dongle, but could only find them with 1 HF input and 1 VHF input, no diversity RTL2832U DVB-T tuners.

Basically, I ve just wasted 3 hours of my time scouring the internet and found no solution :(
