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.

Based on the W3DZZ antenna, this Dipole proved to be very efficient without Antenna Tuner on 80m, 40m, 20m, 15m and 10m bands. With ATU I was able to work on 17m and 6m bands with success. Orientation of the dipole regarding North. Mar 13, 2018 · The W3DZZ is mounted on the mast holding the cobweb in an inverted Vee format and one of the wires come towards about where the picture was taken, the other end would finish up hanging near the hustler antenna to the left. Interestingly after messing about with different positions around the garden I always end up mounting in this way
PA3HGT Rating: 2017-04-07; Nice antenna with a few shortcomings Time Owned: more than 12 months. A well packed antenna when you receive it and you can store it again in the same bag.The overall contruction and the used materials are good and durable.Powerhandling is 1000 (SSB, CW) and 300 W for 7 MHz so real QRO is on 40 not possible.The antenna is working good on 80 and 40 meters, the other ...
Dec 06, 2013 · This popular wire antenna w3dzz is that with small linear dimensions , it can work in several amateur bands . The figure shows a further embodiment of the antenna w3dzz. This version of the wire antenna is designed to work in the amateur bands 1.9 , 3.6, 7, 28 MHz . Total length of the antenna about 67 meters. To connect to the transmitter ...
160-meter band refers to the band of radio frequencies between 1.8 and 2 MHz, just above the medium wave broadcast band.For many decades the lowest radio frequency band allocated for use by amateur radio, before the adoption, at the beginning of the 21st century in most countries, of the 630-and 2200-meter bands.
Of the many desirable properties an antenna can have, the doublet emphasizes having similar directivity patterns over a 4:1 frequency range. This is different from other multiband antennas like a trap dipole (W3DZZ) or a Windom which emphasize the ability to obtain a 50 ohm impedance and a low standing wave ratio (SWR) in all the usable bands ...
