40 and 20 metre trapped dipole


Building an effective HF antenna can be difficult when space is limited. Maybe the full wave delta loop can help?

Antennas for confined spaces
A magnetic loop is perhaps the smallest practical antenna for 80 metres and the only option for some. It consists of a circle or square of metal tubing brought to resonance on the operating frequency by a variable capacitor

40 m short vertical
Antenna for restricted space also an invisible antenna

Indoor Vertical Antenna
The vertical element consists of 2 one meter pieces of aluminum tubing used for hanging curtains

An Indoor HF Stealth Antenna
I found a way to have a reliable Indoor HF Antenna despite my antenna restrictions!

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
