Model AAA-1C Specifications
This document describes the changes made in Model AAA-1C and It is an addendum to Model AAA-1B specification.
Description and Specifications
This amplifier is intended for construction of small wideband active receiving antennas from LF to upper HF bands. The mechanical construction of the particular loop/dipole…
There are two goals when designing a small wideband loop – low inductance and large area. The construction of the loop should be made with the following rule in mind…
The following sections describe in details various parts of the active antenna amplifier. The connection and Control board schematics are shown on Sch.1 at the end of this document…

PC Control of AAA-1 Modes
It is possible to control the modes of AAA-1 from the PC. It is convenient to have such an option e.g. if you have a remote station there must be way to switch the antenna modes via software. The standard COM port can be used for this purpose.The user must build a very simple additional interface board and to use the applied software.
