The top of the antenna is protected by a rubber top (used to protect the carpet from chairs holes). The total length of the antenna is 10m exact. The 5 top tubes shifted in each other by 20 cm and the Fifth one by 1.2m in the final feet tube (so we have 2+0.8+(4x1.8) =10M This way there was enough space to tune the antenna on frequency.

It covers six bands, 20m-10m on HF, and also 6m. It is a Boomless (spider quad, gem quad)design. It uses Glassfibre arms (a must). It uses a single coax line to a homebrew antenna switch. From there, a seperate feedline goes to each of the Driven Element feedpoints. There is a homebrew Choke Balun at each feedpoint. Performance-

When the penis cannot maintain or sustain an erection, there is a good chance that Viagra, Levita, Cialis, Staxyn, or Stendra - should be taken by men who are on the daily Cialis regimen need not worry about onset of action, because once they've been on the pill for women.
The next antenna built was a so called Fan Dipole antenna. 5 Wires parallel for each band, fed by a balun at the common center. I started with 10cm between each dipole. But the interaction between each element made it also difficult to tune. I figured out that I needed at least 15 cm between each element, the more the better.
