HB100 Range extension with Dish Antenna
Taking a look at a teardown of the HB100 module, it appears that the antenna is a pair of two-element patch arrays (one for TX, one for RX) on the back of the board. There's no coaxial out. It'll be very difficult to bodge it into a standard feed horn for a dish.
You might be able to install the module itself at the focus of an old VSAT dish, with the antenna face of the module pointed at the reflector. This isn't super ideal: the patches aren't designed to be a dish feed, so your aperture efficency will likely be pretty awful as you won't illuminate the whole dish and/or you'll have signficant spillover. But, it might work in a pinch.
Either way, keep in mind that you are increasing the EIRP of the module by doing this, and that you may run into regulatory issues if it's too high. I'd suggest learning more about RF and radar before attempting this.
