Abstract: Companies of power transmission lines and telecommunications need to
know the condition of their structures. However, there are ones which are
buried or encased in concrete below-ground. Nondestructive techniques are
essentials to investigate the condition of the rods used to anchor guy cables
in guyed towers. A connector and a matching circuit have been designed to allow
a network analyzer to apply and receive high frequency signals on these rods
and, furthermore, to be able to identify corrosion or holes on an anchor rod
using a promising nondestructive technique. High frequency analysis have been
done on the results provided by simulations and experimental tests through the
reflected signals that come in the input port of the connector and matching
circuit. The high frequency connector, named CHAAF, was fabricated and tested.
