DIY Long Range WiFi Yagi Antenna
15 element long range WiFi yagi antenna for 802.11 b/g/n. How To. Good DIY project using simple tools and parts.
I apologize for the shaky video. I'm an retired person not a videographer. Besides it is hard to record with camera in one hand and cold beverage in the other.
Parts/tool list:
Approx 1 meter of 14 gauge (1.63mm dia) copper wire
Approx 300 mm of RG-8X coax
Approx 1 meter of 9.53 mm diameter (3/8 inch) fiberglass rod
Metric micrometer or ruler
Solder iron and electrical solder
Drill bit less than 1.63 mm in diameter
Hand drill or drill press
John Drew yagi calculator. Compatible on at least Windows XP Home edition
