Help understanding the components between antenna and Pi

If you dont have an inductor, dont worry. You can make a DIY inductor by using a wire from an scarp piece of telephone cable or network cable. Larger the dia of coil, and larger the number of turns in the coil, better the performance. Practically more than 7 turns cannot be squeezed in a splitter box, and coil INNER diameter of about 1/4 inch or 6 mm will be ok (Inner dia = the dia of bolt or drill bit on which you will wind the coil), but it is not critical, you may use somewhat larger or smaller coil diameter.

Second image below is a table of calculation by me for various coil diameters.

I had to hacksaw the top of the box off of mine. Once you had made yours did you encapsulate it of just tape the cut off lid back on? Thinking about it, does it have to be soldered back on for shielding?

Kind regards

I did not hacksaw the top off the box. I removed the back cover of the TV splitter. This cover is a rectangular piece of iron sheet , glued to the housing.

Since the back cover is recessed, it is difficult to remove it. I placed a large flat screw driver in the middle of it and hammered the screw driver lightly. The back cover bent in the middle with edges popped up. I then placed a thin screw driver under the popped edges of back cover, pushed it up, and it came out.

I did not try to put back the back cover as my installation is indoors. In case any one wants, he has to straighten the back cover by hammering, and glue it to the housing like it was done by the manufacturer.
