I have a Saturn Antenna which has been mounted on a Wingard through the roof fitting that allows it to be wound down to horizontal when travelling. Not a big conversion which would be quite an easy job for a competent handyman. I am fairly happy with the Saturn which can be rotated to pick up signals. I have a VAST satellite system for areas with no reception.
I have heard good and bad about both the normal Wingard and the Saturn. Take your pick from the responses in the search section.
If you type in Antennas in the search box it should bring up relevant posts about others experiences with different brands.
One thing I would say is I believe the newer Saturns also have a facility to use it as an antenna for your phone. Their website will give you up to date info.
As for the fridge I have a Vitifrigio fridge which runs on 12 volt only but through a 240 volt to 12 volt Ctek charger when connected to outside power. It is a dedicated caravan/RV fridge and as such are not cheap. ( Already fitted so not a purchase) I have heard people fit house fridges but they only work on 240.Others have used 12 volt/240 volt and some even three way fridges. I think it would depend on the gap left by the old fridge and the power source you prefer.
The antennas in the reply above are for mounting on the top on the van (permanent.) If you wish to have a portable antenna on a pole then there are plenty around like these. Jaycar - Radio Parts - Crazy Sales. They are all similar in that they have a 4 element UHF Yagi antenna in the radome and a folding or telescoping VHF antenna at the back. They have a built in amplifier so you don't have to worry about a separate purchase of a mast head amp. There are many more than I have pictured here.

Both the Wingard and Saturn can be mounted on poles and depending on your set up can be attached to the caravan A frame. Side of Van wherever suits. My hybrid unit is a permanent set up but both the Saturn and the Wingard can be mounted on poles.
There are lot's of fancy, technical and probably expensive antennas out there. I have been using a Dick Smith $99 antenna for close to 20 years, and it has never failed to deliver.

Not sure 03_Troopy, But we currently get the whole 22 Digital Channels in Carnarvon, plus the music ones. I did consider a Sat Dish, but after asking a few questions decided we would be not much better off.
NOTE: we are permanents, and if on the road it would be a different Kettle of Crayfish and Marron.

OK, so it works well stationary where you are, but it may not be so good when you're on the road. Doesn't help the Op with their query unfortunately.

OK we did use it on our last trip around the block without any probs but, I suppose there are some black spots here and there. I am not promoting them, just relating our experience.
