4.9 Low Profile, Hidden and Covert Antennas
There are two users of low profile, hidden, and covert antennas:
• The paramilitary user who will wish to operate from a residence or commercial
building without drawing attention to long range HF communication in
progress.
• Commercial building without drawing attention to the fact that long range HF
communication is in process.
• The amateur radio community (a larger group) finds itself more restricted by
covenants, building codes, and tenant requirements.
