Kenpro rotators come with terminal covers.
This is a KR-400 rotator I bought at a Japanese auction.
However, the used KR-500 elevation rotator I bought in the Philippines did not have a terminal cover.
So I bought a waterproof connector from Shopee, a Philippine online store,
for 229 pesos (about $4).
The original terminal board was removed and replaced with a processed aluminum board.
It was nicely installed.
The black part is liquid tape, which is applied to prevent rainwater from getting inside.
Should I do the same processing on the Rotator KR-400?
I ordered a 6-core control cable from Shopee.
20m 6-core 18AWG cable costs 2,700 pesos (about $48)
