We are in the north west corner of Victoria in the Mallee. Our TV antenna are mounted on towers in the homes as a normal roof antenna doesn't pick up a signal. Our caravan park has an antenna but it is only on the managers office. My question is this. Is there a device that we can connect to the antenna and repeat the signal so visitors to the park can receive the signal through their caravan mounted antenna?

Retransmission is technically possible, but there are several regulatory and contractual hoops that one has to jump through first that would likely push it out of your pocket's reach.

 

How many sites are there?  It might be feasible to install a cabled distribution system that visitors could plug their equipment into, or even 'toss the wire over their antenna' to induce enough signal in it to get reception.

Thank you for your reply. Cabling in the area is not a real option at the moment. We are investigating the repeater through the air option and its costs first. The hoops we need to jump through will be looked at once we have settled on the equipment the we need to achieve result we are looking for.

What would probably be the best option would be a set of infill repeaters.  They are off the shelf items and take the signal from, say the antenna on the manager's office, recondition it and retransmit it on the same frequency as the main broadcast.  Dig around with Google, but it'll make a mess of your pocket.  You'd then need to get a licence from ACMA to transmit on the relevant frequencies (this will cost and won't be easy) and finally an agreement with the originating networks to re-broadcast their service (don't expect this to be easy either).

 

They require professional installation, as amongst other things, there must be sufficient isolation between the receiving antenna and the transmitting antenna otherwise nasty things happen.

 

A dodgey option would be to simply slap an antenna on the output of a high gain distribution amplifier which is fed from the manager's antenna.  Again this requires good isolation between in and out and is prone to many other problems to boot, not to mention you being responsible for any RFI it causes to anyone in the area. and ACMA takes a dim view of that.
