Yes, many have hacked a DirecTV or Dish Network dish before. Quite undersized, but would receive the 97w KU stations with an LNBF swap. Make a template to set the LNBF face angle and distance from the reflector. Remove the current circular polarity LNBFs and make a bracket to hold the replacement linear LNBF in the correct centered position. Remember to set the polarity skew.
would probably also work well for NHK on 101W and possibly for PBS on 99W. I used one for a while on 30W. Just keep in mind that because it's undersized for those satellites, it might work fine in clear weather but won't have much margin to account for signal degradation during rain/snow
If you can find one, the Shaw / Star Choice 75e ellipticals are great for use on 97, 99, and 101W. They are really just rebranded ChannelMaster 75 cm reflectors and use linear LNBFs by default out of the box.
I have read that some have converted this type dish but after giving it a good look, it's the lnb conversion that is the bottleneck. Does anyone have a picture of their attempt to configure the lnb? I watched a video on youtube from the save it for parts guy and he used duct tape! Guess it worked but I'm thinking something a bit more permanent!
Thanks to all for your interest and replies...
