If I understand correctly you want to connect a television and TV tuner on your laptop to single antenna.
In that case you will need to buy a spliter - something like this

If you plan to use TV antenna for Wireless networking - forget it ;)
The systems are done for different frequencies, TV antenna is used for accept signal only, than there you have installed a series of filters and amplifiers,...

No I am simply trying to convert my current wired system into a wireless one.

I connect to a very good external TV antennae via a RF wall socket, I use a RF splitter and cables to run the connection to all the TV's in the apartment independently.

I would like to know whether there is anything I can plug into the RF wall connection and then wirelessly transmit the antenna signal to each TV individually in exactly the same way I do with the cables. In essence a wireless splitter and sender connected to the RF wall connection which can then transmit to a receiver on each TV like a video transmitter sender receiver system.

I see. I'm afraid that it can not be done.
TV antenna signal uses big amount of bandwidth - cca. 500 MHz and I think that there is no available so much bandwidth space in public available frequencies. You need to transfer all TV channels even if you look only one at the time.
In WLAN you have 13 channels with 22 MHz bandwidth packed in just 82 Mhz band. In reality you have only 3 channels that don't overlap and interfere with each other. I just wanted to show the lack of bandwidth even in common used cases.
The only option is A/V wireless transceiver - it transfers audio and video signal from different sources and you will need to have tuner at the RF wall connection. But really I don't see a real use for your case.
