Hi hi, this Dummy Load casing was made from King Cup Sardine can. For sure it can be used without worries because it is certified Halal by JAKIM.
The idea of constructions is like this
but using more resistors. Use the Ohm’s Law to get the 50 Ohm impedance.
Then encase the resistors with a tin can.

How to make it?

Use ohm’s law to make a 50 ohm resistance. Use carbon resistor not metal film nor wirewound. the higher the wattage the better.
I don’t remember my resistors quantity and resistor value each but not less than 20 pieces connected in parallel…
maybe next time I’ll documented my experiment..
But the idea is like the image below….

hehehe whoever cannot understand the principle, he/she is a real dummy…. ROTFL…

King Cup.
Next time kalau nak buat kena cari cap Pertima, kena sokong Buatan Bumiputera. Anak Syarikat Kerajaan Negeri Terengganu hehehe.
