* Note, the above dimensions are longer then required to permit adequate wire for forming elements.
The following table has precise per side measurements.
Be sure to cut elements from the appropriately labeled spool of wire
Table IIb 3 ELEMENT QUAD DIMENSIONS (PER SIDE) Element Framing Dimensions
BAND
10 M
Reflector
107.5"
Driven El
105.0"
Director 1
100.8"
The total length is 4 X the above dimensions. In order to make splices and connections
and additional 4 inches must be added to Reflectors and Directors. Driven elements need
an additional 24" for 10m/20m, 18" for 12m/17m and 6" for 15m - This is IMPORTANT.
This additional Driven Element length is essential if the MT-3 matching transformer
will be used!
