Part 3 - Enhancement Study

In order to look for better result, Antenna Construction part 3 is about adding a balun and an amplifier for stability improvement.  

A balun is used to prevent feedline pickup. With it, signal reception will not be interfered even when people is moving around the antenna. 

Our balun is a EMI choke made by winding the coax through three ferrite toroidal core three times.

An amplifier is also added to enhance the signal strength and reliability.  A RCA 10dB 50-900MHz amplifier is used.

Besides of using my camera tripod as it's stand, this antenna setup is almost perfect for receiving the local high quality OTA HD programmings.
