My "secret antenna" is the Windom.

44 feet (13m) of wire on one side, 88 feet (26m) on the other side, fed
in the center with a 4:1 balun. (many hams use some flat twinlead
between the feedpoint and the balun, allowing the balun to be fastened
to a pole or something to avoid the physical straing at the feedpoint)

Works without a tuner on 80, 40, 20, and 10 meters, and with the
autotuner on most rigs on 15. And it's effective. And easy to build!

anyone have a good ideia to build a multiband wire antena?

According to Cebick, W4RNL and his modeling, the best 10m through 40m
antenna is a wire of 44' in lenght, horizontal fed with ladderline.
Gain on these bands as well.

A simple inverted-L (a vertical wire plus a horizontal wire), of no
particular length is about the best you will ever have. The higher
the
better. You will need a ground connection such as half-dozen,
shallow-buried radial wires, between 10 and 20 feet long. Include
any metal
water pipes with the radials.

An overall wire length between 100 and 150 feet does better on the
lower HF
frequencies and on the MF broadcast band. Between 40 and 100 feet
does
better on the higher frequency HF bands.

They'll never get it. It's too simple.
