Some Criteria For Evaluating Antennas
9. Are the antenna drain holes open?
They are placed at the bottom of the antenna for draining internal moisture.
Periodic inspection of these openings is the responsibility of the owner. They
must remain clear of debris to preclude corrosion from internal condensation.
Such damage can drastically affect performance and is not covered by
warranty.
10. Is the antenna intermittent ?
It is a good idea to shake the antenna during the above tests to ensure there
are no mechanical intermittence. Poor connections may lead to RF
intermodulation products. Water entering the antenna may lead to electrical
intermittence which subside when the antenna dries out.
