40-15m antenna Sloper
The tower guy wires could be used as additional antenna radiators. The antenna that most suited this application was a 40m band sloper as the guy wire to be used was slightly longer than a 1/4 wave length at 7 MHz

Single 5/8 Flower Pot Antenna
Construction of the Single 5/8, whilst a little more involved than the basic half-wave antenna, is again fairly simple
Self's building of a HF2V, vertical antenna for 40 and 80m
First I regarded the antiresonant circuit Groundplane. There the antiresonant circuit comes to a 1/4 wavelength, related to the higher operating frequency 7 MHz
Semi-vertical Trap Antenna for 1.8 MHz, 3.5MHz and 7.0MHz
Having made many contacts around the World using the Tri-Band Trapped Dipole 18MHz, 24MHz and 50MHz, John decided to add extra Traps in order to include 14MHz, 21MHz and 28MHz
