After month of reliable performance of the part 3 testing antenna, it is now time to wrap things up to produce an antenna with it's own stand as a finished product.
 |
| The body of the stand is an aluminum angle (1/16" x 3/4" x 3') with a PVC tube on the top and a small particle board as base plate. A 3/4" PVC tube of 3 1/2" long is installed on top of the aluminum angle using 2 screws. |
 |
| A 4" x 4" base board. A short piece of aluminum angle is used as corner brace to mount the vertical aluminum angle to the base board. |
 |
| Use the antenna rod taken from previous Antenna Construction Part 2. |
 |
| A reducing bushing is mechanically modified with a slot for the antenna rod to fit in. |
 |
| Put the antenna cable through the bushing. |
 |
| Use hot melt glue to glue the bushing to the antenna rod. |
 |
| Put the antenna cable through the PVC tube. |
 |
| Cover and fit the antenna bushing to the PVC tube. The antenna rod can therefore change it's reception direction by rotating the bushing on top of the PVC tube. |
 |
| The antenna's reception direction is changed about 90 degree. |
 |
| As before, coil the antenna cable with three ferrite toroidal cores to form a EMI choke. |
 |
| The antenna design is simple and small in foot print. |

 |
| The final version is to add the amplify to the antenna in order to enhance the signal strength and reliability. A RCA 10dB 50-900MHz amplifier is used." |

Conclusion
It is time to go completely cable-free, adopting over-the-air HD broardcasts and online streaming services. In fact, the OTA broadcasts programming is the best 1080i HD video quality you can get, which is much better than through the scrambled cable transmission.
