Before the adoption of red dot laser alignment tool, I have used several measuring tools to center the feedhorn. In addition, I also make a wooden dow that fits into the throat of the feedhorn with a metal rod centered and parallel with the throat of the feedhorn. However, it is quite hard for me to make sure of extremely accurate and straight rod, but the adoption of red laser dot generating laser alignment tool has just helped me a lot. The accurate and bright red laser dot emission can instruct me to make super accurate and precise dot targeting and positioning much better than ever before.
Outside the red dot projecting alignment laser tool, it selects external DC input power supply or rechargeable battery box as its power supply source. For close distance dot positioning, low powered laser alignment tool with 3.6V operating voltage electric power supply is enough to support bright and visible red laser dot generation on all working surfaces. In addition, higher output powered red laser dot projecting tool is just selecting higher operating voltage of 4V. Only if users are selecting proper configured laser alignment tool with proper output power and operating voltage DC power supply, users can just obtain the most precise and non mistake dot generation perfectly.
