In Singapore space is limited, and in our appartment it is difficult to setup any HF antenna. Our balcony is the only place where I have a space to mount something. Even there, officially nothing is allowed to extend out from the building.
I decided to setup a simple vertical, using a telescopic fiberglass pole, which I can pull out temporarly, when it is getting dark. The pole has a total length of 10 m, approx. 1 m (the lowest segment) safely mounted to the balcony railing and sidewall.
10 m fiberglass pole mounted to the balcony railing in the 17th floor.
The actual antenna wire is fixed to the pole using Velcro strips. The horizontal wires on the picture are part of my short linear loaded dipole for 15 m and 17 m.
Antenna extended to 10 m
Rubber protected pipe clamps to secure the segments and Velcro strips to attach the antenna wire to my telescope fiberglass pole. Allows quick extension and retracting of the antenna.
VSWR of 1.2 at resonance frequency 7.050 MHz, using only one radial around the outer wall of our appartment
