20m & 40m trapped vertical antenna
With the wire lengths shown and supported by my 9m squid pole, I got SWR less than 1.3:1 on 7.100 MHz and 14.200 MHz

9 band vertical HF antenna
May be it sounds crazy, but this antenna realization is my former idea of using any random wire as HF multiband
27m Titanex vertical
The antenna tuning unit used with this 27m Titanex vertical was originally designed to operate on 40, 80 and 160m

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
