Antenna Hacks

- Y10-7-13 VHF Antenna: two different versions adding 3 and 5 additional directors and a planar reflector.  Approximately +2 and +3dB gain improvement, respectively.

- DB8 UHF Antenna: swapped out the stock combiner and harness, closed the triangles, and added a trough reflector.  Aproximately 3 to 4 dB gain improvement (this is the "Old" DB8).

- CM4228HD Nist Harness Here is an implementation of the harness design by Ken Nist, publisher of "The HDTV Primer".
