Replacement cost of Tatasky SD STB and LNB

[ABCDEFGH]

The person who came to fix this issue replaced LNB which was originally from SHARP company with TS branded LNB and some two connectors which got rust due to rain. I am having 2 wires from dish to my set top box. I am subscribed to annual pack hence TS did not charge me visit fee but charged LNB cost as 300/-

I am not sure if its the correct price TS charged me.

Ya, the price of LNB used for TS+ HD box will be more because it has 2 outputs unlike the LNB used for normal box which has only 1 output

although no idea what is the exact price
