Lo+Hi-VHF 1-Bay Bowtie
1. Lo+Hi-VHF 1-Bay Bowtie  (24 Nov 2012)
Lo-HiVHF (Ch2-13) 1-Bay Bowtie analyzed using 4nec2 after optimizing via nikimil's Python scripts.

Provides more Gain than Stick Dipole or Folded Dipole across BOTH Ch2-6 Lo-VHF and Ch7-13 Hi-VHF Bands.
However, narrow beamwidth on Ch7-13 requires careful aiming.

Optimized size is BIG (15.75-ft Wide by 4.25-ft High), using 1/4-in O.D. Copper (may use larger, incl. 3/8-in Aluminum):
Each of Six Whiskers = 92-inches, Top-Bottom Tine Separation = 51-inches & Feedpoint = 5-inches.

V-Stack Hi-VHF Circular Loops
6. V-Stack Hi-VHF Circular Loops  (16 Jul 2014)
Vertically Stacked Hi-VHF Circular Loops analyzed using 4nec2.

Three Versions are presented:
a) Lossless RF Combiner Mod emulated by Two Independent Sources
b) Two Equal-Length 300-ohm (Twin-lead) Transmission Feedlines
c) Hollands Vertical Harness interconnects Stacked Antennas

[In Hi-VHF Band, all Dimensions can be rounded to nearest 1/4-inch.]

#################################################
a) Lossless RF Combiner Mod emulated by Two Independent Sources:
Hi-VHF Raw Gain = 11.2 to 11.3 dBi, F/B & F/R Ratio Minimum = 15.1 dB and SWR (300-ohms) under 2.9.
ACTUAL RF Combiner Loss will reduce calculated Gain by about 0.5 to 1.0 dB.

Circular Elements = 1/4-inch Copper Tubing (QICT).
RS = 13.0-inches = Separation between Reflectors and Circular Loops
VS = 50-inches = Vertical Separation (Center-to-Center, in inches).

#################################################
b) Two Equal-Length 300-ohm (Twin-lead) Transmission Feedlines:
Hi-VHF Raw Gain = 10.1 to 10.3 dBi, F/B & F/R Ratio Min = 18.4 dB and SWR under 2.3.
Rain, Snow & Ice will significantly increase Loss in the Twinlead.

Circular Elements = 1/4-inch Copper Tubing (QICT).
VF = 0.83 = "Typical" Velocity Factor of 0.83, cheap R-S Twinlead measured low as 0.77.
OPTIMIZED DIMENSIONS:
RS = 13.5-inches = Separation between Reflectors and Circular Loops
VS = 33.87-inches = Vertical Separation (Center-to-Center, in inches).
Lx = 20.87-inches = OPTIMIZED Extension to Length (in INCHES) of Transmission Line:
Lt = 26.31-inches = Lx-11.5+VS/2 = PHYSICAL Length (in INCHES) of Each Transmission Line
Le = 0.8052-meters = Lt/(39.36*VF) = ELECTRICAL Length (in METERS!!!) of Each Transmission Lines

#################################################
c) Hollands Vertical Harness interconnects Stacked Antennas:
Hi-VHF Raw Gain = 11.5 to 10.3 dBi, F/B & F/R Min = 16.1 dB and SWR (300-ohms) under 2.3.

Circular Elements & Harness = 1/4-inch Copper Tubing (QICT).
Gap = 0.75-inches = Feedpoint Gap in Circular Loops.
VS = 50.0-inches = Vertical Separation (Center-to-Center, in inches).
OPTIMIZED DIMENSIONS:
RS = 13.75-inches = Separation between Reflectors and Circular Loops
Xh = -6.31-inches = Harness X-Axis Separation from Plane of Circular-Loops.
Yw = 2.21-inches = Y-Axis Width of Harness Separation.
Zh = 17.87-inches = Length of Harness Wires between Balun Feedpoint and Diagonal to Circular Loop.
Ld = 7.71-inches = Lengths of Diagonal Harness Wires to Gap in Circular Loops.

Lharn = 52.5-inches = 2*Zh+2*Ld+2*(0.67 for wire loop ends) = Harness Wire Total Lengths (2 required).

Hi-VHF Goalkeeper Quad-Trapezoid+Spurs
8. Hi-VHF Goalkeeper Quad-Trapezoid+Spurs  (22 Jul 2014)
Hi-VHF Goalkeeper, a Quasi-Omni [accidental] variation of the Quad-Trapezoid+Spurs
was analyzed using 4nec2.

Provides Bi-Directional Pattern firmly aligned along the X-Axis with 100-110 degrees Beamwidth
and NULLs to the sides.  Although Horizontally Polarized, it also provides both
Right-Hand and Left-Hand Circular Polarization.
