30m 4lelment is a home made yagi antenna with 1: 1 balun and hairpin matching.

The best thing I did was to design a 30m inverted antenna with a beam antenna in 2017, which I think was the best thing and it gave me great strength in acquiring many countries. It is very good to be able to receive reception preferentially.

  The characteristics of the antenna are broadband, vswr 1: 1
Fixed transmission and reception are always good.

 

The element has no traps and can withstand several kilowatts. To reduce the effects of snow and wind, round rings are machined from the element coupling joints, secured with wrench bolts, and then made using compression tubes and rubber caps. It is used to increase strength and strength.
                                        

       

Antenna adjustment method.
1. After connecting the 1: 1 balun and connecting the coaxial cable, when the antenna height is 10 m, use the meter to check the resonance frequency, adjust both ends of the element, and do not tighten the two elements completely.

2. Connect the antenna to the master pipe,
Use the meter to connect and adjust the elements.
Resonance frequency, impedance and VSWR

Coaxial cables are wound with tape and hairpin adjustment bolts and elements.
Tighten both ends of the pipe.

3. If you need to re-adjust
Adjust the drive element and hairpin to match.
If you have an antenna
Impedance is 48 ohms and 50 ohms in vswl.
The bandwidth is very wide and vswr is 1: 1.
No fixed changes
