W3DZZ Antenna Moonraker supply a whole range of wire trap dipoles covering from 2 to 5 HF bands (MTD1; MTD2; MTD3; MTD4; MTD5; MTD6). Diamond also produce trapped wire antennas, the W-721, W-728 and W735.Here is my home HF antenna. It is an off centre fed dipole, with 10 feet of vertical radiator. It needs no tuner on 40m, 20m and 10m. It also works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m, although the coax losses will be higher. Some of the Topics: Vertical dipole and sloper in free space, over perfect or real ground – sloper with several elements – feeding sloper antennas – multi-band sloper – W3DZZ and double Zepp as a sloper antenna – multi-element sloper antennas for multi-band operation – special types of halfwave sloper antennas and much more!

TRAP-dipole - the W3DZZ antenna for 40 and 80 meter band - updated nov. 2010. HOW TO.... Before you start, bee sure that you know exactly where you would hang the dipol. I hang it in the tower up 9 meter, and the ends is inverted to about 4,5 meter over ground with an angel about 140 Deg. in feedingpoint.

Product description The attempts to introduce the three-band dipole w3dzz+3 into the world market led to an interesting acquaintance with a new design of an old antenna which additionally had the bands of 21 and 28 MHz.

Aug 19, 2020 · The Antenna is a 420mm PVC cylinder with saddle type mounting bracket and 7 metres of high quality RG58 cable terminated with an RCA Phono plug. The end caps are force fitted and the cable entry is through a waterproof gland.

Trap dipole for 80m,40m,20m,15m and 10m. Length 36m, with sealed balun, connector PL, max. power load 1000 W SSB/CW (300 W at 40m).The 1/4λ transformer ensures that the antenna is resonant in addition to a conventional W3DZZ on 14 MHz. Between the transformer and the trap is a short piece of cable, which acts as capacitance. Thereby a resonances can be reached at 15m and 10m.

L'antenna descritta in questa pagina è una "W3DZZ". Ora, molti sanno che cos'è, ma per quelli che non la conoscono cercherò di spiegarne il funzionamento a grandi linee. Si tratta di un normalissimo dipolo con 2 trappole, le quali hanno un valore ben preciso.
