In order to receive 437 MHz (70cms) DATV on a standard satellite STB or MiniTioune , you need to up convert the signal to L band.
Luckily there is a consumer device available in the USA which is used on cable networks to up convert UHF signals to L Band where they are then received on a standard satellite box. The units are made by a company called Zinwell and known as SUP-2400. They are available on ebay but only in the US and so are stocked in the BATC shop.
However, before use on 70cms, they either require hardware modification as described in CQ-TV 239 and the document available for download further down this page, or the use of the Diseqc controller as described in CQ-TV 250 - details available here - to work on DATV.
