May 30, 2012 · The purpose of this construction is to enable the realization of an HF antenna called W3DZZ with minimal equipment and low cost. It allows traffic on the bands 3.5 / 7/14/21 and 28MHz.the diagram Constitution of the antenna- A central dipole cut to operate on the tape 7Mhz.- 2 “traps” or oscillating circuits tuned 7.050Mhz.-…
The W3DZZ design has at least three basic variables: - Length of the inner dipole sections - Length of the outer dipole sections - L to C ratio of the traps. By careful adjustment, the W3DZZ antenna can be tuned to resonance on at least three bands (typically 80/40/20) and the 15/10 meter bands will be pretty close.
10 m Band Delta Loop DX antenna for 28.000 MHz This is a 28.0 – 29.7 MHz 1/1 wave antenna. Covers 28.0 – 29.70MHz Made from copper wire.
ANT.W3DZZ + 5 1000w dipolo para 80m, 40m,20m,15m y 10m. Longitud 36 m, con balun sellado, conector PL, máx. carga de 1000 W SSB / CW (300 W a 40 m).El transformador de 1 / 4λ asegura que la antena sea resonante además de una W3DZZ convencional en 14 MHz. Entre el transformador y la trampa hay un pequeño cable que actúa como capacitancia. De este modo, se pueden alcanzar resonancias a 15 m ...
