[QUOTE="BombedOne, post: 805762, member: 300998"] Thanks. I know that LNB cooling is not the best way, but I would disagree that it is more expensive than larger dish. Now I have 1.5 meter primefocus dish. If upgrading, should get at least 2.4 meter one. For the 2.4 meter one, I have the following choices: 1. Prodelin 1251, 1700 euro+feedhorn. Need to pre-order, delivery time 2 months. 2. Laser Sat from Turkey, about 900$, delivery, import duties and so on will rise price up to 1500$, need to import by myself 3. Some bulgarian manufacturer, price about 1100$, import duties and delivery and so on - up to 2000$ In comparison, that cooling system costed me less than 200$. It consists of several peltier modules chained together, and huge cpu heatsink with fan. Inverto C120 LNB being cooled, and whole assembly is encased in foam, to prevent condensation and from outside, mylar reflective foil is added. Needs about 20 minutes to reach -60C [/QUOTE]
