Ahoy mate, for an LNB (Low Noise Block converter) for your satellite dish, expect to pay around R150-R250 depending on the type. The top result is the Universal HD Satellite Receiver Waterproof LNB for R148 - a basic single LNB that'll get the job done. If you need multiple sat inputs, consider the Dtv Dual Lnb: STL-02 for R245 or the Universal 8 Output H & V Split Ku Band Lnb TG88HD which allows connection of up to 8 satellites - though it's a might more costly. Apologies but I don't have full prices on some LNB accessories that came up. Feel free to search PriceCheck yourself too - they've got a big old catalogue to explore. Let me know if any of these sound worthy for your satellite adventure!
