KK1CW Repeater Antennas How They Are Constructed
See an Example 2 M Antennain Excel
Note 1: The 1/2 wave elements are made with 50 ohm coax with the outer
conductor removed.The center conductor is
placed inside each one of the 3/8 inch copper tubing elements
Note 2: The antenna is housed in fiberglass designed for RF use.
Fiberglass and other
material used to house the antenna
are very important because
the lengths of the antenna elements
will or may be affected.
Note 3: The 5/8 wave element on top of the antenna will provide enough
downward tilt and low
angle of RF at the horizon to make it very
affective for long
hauls. For more gain just add more 1/2 waves elements.
Anything more or less
than 5/8 wave at the top will give you less RF
at the horizon.
