Eek. Three splices and you expect it to work properly?

If they were well-made splices, there would be no loss at
all. By well-made I mean soldered and taped. Or nicely done
with wirenuts or other proper solderless connector.

Every time you splice a wire you loose 2-4db per splice.

Not in this life. If you do the splice well the loss is
absolutely positively negligable. If you do it badly enough
to have appreciable loss, then the splice will probably fall
the rest of the way apart by itself, pretty quickly.
