433 MHz Directional Antenna Lora Yagi Antenna

What is 433 MHz Directional Antenna Lora Yagi Antenna?

The 433 MHz Directional Antenna Lora Yagi Antenna style CTRF-ANTENNA-YAGI-0433-10037-SMA antenna item is a high-performance 433 MHz Yagi Antenna Directional Lora Antenna 8 element Yagi-Uda antenna manufactured by C&T RF Antennas Inc for outdoor wireless network applications.

433MHz Yagi Antenna DIY

Antenna name: Half wave oscillator 5 elements U-band Yagi antenna

Vibrator Material: 8mm outer diameter refrigeration copper tube.

Main beam material: PVC hot water pipe (harder, bendable), outer diameter 17mm.

Support rod material: PVC water pipe, outer diameter 32mm.

Oscillator element length: reflector 330mm, active oscillator element 160mm two, director one 310mm, director two 300mm, director three 290mm.

Center frequency: 438.5MHz

Barron: feeder winding 4 turns, diameter 50mm.

Feeder: 50-5, Length 14m.

Adjustment: First, place the adjacent units at a distance of 140mm, then connect the standing wave meter and launch at the desired frequency point, adjust the position starting from the reflector, in order of reflector, leader one, leader two, and leader three. Move their position on the main beam to the minimum standing wave coefficient.

After the adjustment, if the standing wave coefficient cannot be reduced to below 1.2, the feeder can be cut short to test, each time cut about 10-50 mm, the experiment can be successful 4-5 times. My experimental results are less than 1.1 standing waves.

Other: After the vibrator position is adjusted, the card and the main beam are fixed with a hot melt adhesive.

Trial use: QTH Beijing city center, Tonglian Mentougou district Miaofeng Mountain scenic spot, straight line distance 33Km, antenna height 6m, transmitting power 4.3W (antenna oscillator feed power 2.4W) each other reported signal 59.

In the above experiments to the actual effect, oscillator size and location may deviate from the theoretical value.
