Get a roof mounted aerial.

Get a roof mounted aerial.
are they that good??might have to have a look
I get a near perfect signal with my free view tv with just a mini mag mounted rubber duck, never needed to hang it out the cab, I think a lot depends on the quality of the receiver rather than just the aerial.
Get a mag mount roof aerial about £20 from Pure check their website the difference will amaze you. At least
50% improvement over the window thing.
That’s a strange one, my pure highway worked perfectly with the standerd Arial on the windscreen, only issue I had was the powerlead kept breaking
the mag mount is the best option used to use the window one but certain areas used to lose the signal changed to the mag mounted one spot on 
Mine was hopeless until I bought a mag aerial and stuck it on the cab roof, get one with a long cable and tuck it in neatly. Worth the money, shame they dont supply these with the unit.

Mount your dab aerial on the opposite side of the cab from your radio aerial and at least 10inches from the glass, that’s what it says in my dab book and I get a good reception in most places, except Basingstoke for some reason
