UHF H2 2-Bay Bowties + Screen Reflector
4. UHF H2 2-Bay Bowties + Screen Reflector  (9 Feb 2015)
UHF H2 2-Bay Bowtie with Screen Grid Reflector Analyzed using 4nec2 after determining OPTIMUM Dimensions
using nikiml's Python Optimization Scrips.  Performance is significantly better than ANY other 2-Bay Bowtie.

Two versions are Optimized and Analyzed....the second clearly outperforming the first:

a) H2 (9.5"x12") 2-Bay Bowtie with 24"Hx24"W Screen Reflector (Grid=2"Hx4"W),
with Hi-VHF Gain to REAR on lower Channels:

UHF Raw Gain = 10.3 to 13.6 dBi, F/B & F/R Ratio Min. = 15.4 dB and SWR (300-ohms) under 2.3.
Hi-VHF Raw Gain = -2 to 8 dBi FORWARD and to REAR Raw Gain = 6.9 to 7.3 to 2.5 dBi with
Hi-VHF F/B & F/R = 10 to -5 dB and SWR (300-ohms) = 125 to 60.8.

Dimensions (inches):
BowLen = 9.5 = Bowtie Whisker Half-Length,
ZBowII = 12.0 = Distance between the Centers of the two Bowties,
TineSep = 8.25 = Bowtie Tine Separation,
BowSwp=0.0 = Bowtie Forward Sweep,
FedSep = 1.75 = Separation (in inches) between two FEEDLINE wires,
RS = -4.75 = Separation between Bowties and Reflector.
Screen Reflector = 24-in H x 24-in W, 2"Hx4"W Grid (1"Hx2"W would improve F/B & F/R Ratios).

======================================
b) H2 (10"x15") 2-Bay Bowtie with 36"Hx36"W Screen Reflector (Grid=1"Hx2"W), with significantly
higher UHF Gain and more Hi-VHF Gain aligned FORWARD:

UHF Raw Gain = 12.9 to 14.5 dBi, F/B & F/R Ratio Min = 22.5 dB and SWR (300-ohms) Under 2.8.
Hi-VHF Raw Gain = 8.2 to 8.6 dBi, F/B & F/R Ratio = 9.8 to 15.9 dB and SWR (300-ohms) = 93 to 31 is Excessive.

Dimensions: (inches)
BowLen = 10.0 = Bowtie Whisker Half-Length,
ZBowII = 15.0 = Distance between the Centers of the two Bowties,
TineSep = 10.0 = Bowtie Tine Separation,
BowSwp=0.0 = Bowtie Forward Sweep,
FedSep = 2.75 = Separation (in inches) between two FEEDLINE wires,
RS = -5.0 = Separation between Bowties and Reflector.
Screen Reflector = 36-in H x 36-in W, 1"Hx2"W Grid.

Selro Backs, Connectors & Others
13. Selro Backs, Connectors & Others 



Here you will find ways to identify Selro pieces that are unsigned. Connectors on bracelets are a good start, plus backs of pieces, construction and other identifying marks.

Just a note: These overlapping V connectors are not only found on Selro pieces but they do help to identify pieces that have other attributes.

Also, not all pieces will have back bracing and it appears not to be found on signed pieces. Many large Selro pieces are out there that do not have this feature.

Please keep in mind that not all Selro was created the same way and that not all pieces will have the same kind of backs, connectors or clasps. There are many different styles. This page is a work in progress.
