TV aerial Question for the 'lecky types (1 Viewer)

[GWAYGWAY]

I have made an external aerial for my motorhome that has a pole to allow me to rotate it to get a signal from different transmitters. When I travel around, I do not know where the transmitters are, OR what type of waves horizontal or vertical polarity they transmit on. I have just bought another identical Labgear aerial to go on the same pole . Question is, can I fit them intermeshing dipoles vertical and horizontal and can they go together that way, they physically fit but will I lose the signal from interference of the other dipoles, and can I couple the wiring down the same lead????

I think you will lose some of the signal. A TV aerial can also act as a transmitter. For example, I've seen in the Highlands an aerial on a hill top which was pointed to the transmitter. This was then connected to an identical aerial pointing down to the house below. No amplifiers involved.
But I suspect the loss would be manageable but ideally having two leads would be better.

There are apps available which will tell you which direction the transmitter is and which way they are polarised.

There are apps available which will tell you which direction the transmitter is and which way they are polarised.

Most of them are 'near enough this way' directional, which was fine for the old analogue signals but digital needs to be pointing 'cross hair' accurate at the transmitter unless it's VERY close by, in which case its doubtful you need a finder.

Have a look where the local aerials are pointed - you may need binoculars sometimes.

There are systems available to combine two aerials but they are provided as an assembly with matched aerials, matching sections of coax, and a matched combining device. This careful design is necessary to ensure that the output of one doesn't cancel the output of the other.

Hymers have a built in aerial there should be a lead near your TV postion it will have an F connector on the end so you will need an adaptor. You also need to turn on 5v antenna power on the tv to power the built in amplifier.

Most of the time my Hymer built in aerial works ok. If I need an external directional one I use Antenna Aligner, an iphone app, to line it up. The app locates the nearest transmitters and shows expected signal strength (good/poor/bad), direction (degrees) and polarity (h/v). Having selected a transmitter it jumps to a compass and gives you a rotating arrow to show where you should point the aerial.

My Avtex STH3000 aerial has a built-in amplifier, and from my experience is not too fussy as to which way you point it, thereby making my Ae Location App pretty well redundant.
