HI fiddlestix, I have one of these aussievan easy tune tv antenna..
http://aussievan.com.au/shop/easytune-antenna-system/easytune-tv-antenna/range from about $229
I have tested it at home and it worked well (Brisbane), and took it on our recent trip and at one spot I could only pick up SBS (Standown Park outside Tin Can Bay), it works fine at home and a mate had one a fingal back in MAy this year and i watched the footy on it no worries at all.
Anyway, I had mine setup on the annex side at the drawbar end adjacent to the safety support pole and used a couple of zip ties (probably need to find a better option) to keep it in place, these wrap around the upright wind up supports of the Swan, the pole was then hidden behind the flap that attached to the annex. The reason I put it on this side and not the side the antenna plug is that it was easier to play around to get the signal than on the otherside, plenty of coax cable to plug it in..
Anyway, I have only had mine a couple of months and used it once but i was thinking of buying a satelitte so I can take my foxtel box away with me next time...
Regards
Scott
