What is the weight of the Vansat? Should it be mounted near the roof edge of the van? In your opinion, which of the Vansat and Promax is the better OVERALL unit? Thanks
The VanSat Bluestar is 14KG on the roof. It doesn't have to be mounted near the edge as the weight is well distributed and it comes with a 500mm long rectangular aluminium plate that is glued to the roof and spreads the load. Although the 2 systems work on different principles in order to increase gain, the Vansat will always offer more of a buffer over and above the minimum signal required for the VAST or Foxtel box to operate and "lock" on signal. This is not to say that the Promax won't work across the country, it just means that the received signal will always be a little less so if the weather conditions were unfavourable then the Promax may not be able to receive all channels in the weaker NW Western Australian regions. I think the most important consideration though (over and above signal levels) is the benefit of wind resistance. The Promax is unaffected by wind and can be left up in all weather conditions whereas the Vansat (and all other traditional dish systems) are affected by heavier wind and tend to "flutter" causing signal break up. Also, the compact size means the Promax will fit in tight spaces on roofs. The Promax is heavier though at 20KG so I would consider installing it closer to the edge of the van unless the roof has been re-inforced. The Promax is also slightly higher at 285mm as opposed to 210mm for the Vansat so a few things to consider there.
