The DXE-NOISELOOP is a kit of parts to build this receive-only portable directional HF loop antenna, which measures only 48 by 24 inches plus 36 inches of mast-handle. It may be used while walking or stationary with your portable HF receiver. Oriented vertically, this loop antenna features a cardioid pattern at the horizon with a deep null of up to 30 dB rejection. It is an excellent tool for locating noise s

The DXE-NOISELOOP is a kit of parts to build this receive-only portable directional HF loop antenna, which measures only 48 by 24 inches plus 36 inches of mast-handle. It may be used while walking or stationary with your portable HF receiver. Oriented vertically, this loop antenna features a cardioid pattern at the horizon with a deep null of up to 30 dB rejection. It is an excellent tool for locating noise sources from 1.8 through 30 MHz and for low-noise, general coverage reception from the AM broadcast band through 30 MHz. An optional Preamplifier-Attenuator Unit, DXE-NL-PRE-ATT-1, may be attached to the loop mast handle for enhanced operations. An IC-705, a portable SW or a handheld HF receiver are excellent choices for searching for local noise sources with the NOISELOOP, around the neighborhood and even around your own home.
This Portable Flag Antenna Kit includes everything needed to make the antenna: fiberglass tubing for the frame and handle, mounting plate, separate PC boards for the bifilar wound transformer and load resistor, antenna wire, coaxial cable with male BNC and stainless steel hardware. Simple hand tools and a solder iron are required for assembly. Included instructions detail assembly. This kit will typically take between 1 and 2 hours to build.
The WD8DSB Portable Flag Antenna design has become a real game changer in direction finding of RFI on MF and HF frequencies, and you will also find it an invaluable tool when hunting RFI due to the following key features.
*Unidirectional (unlike a tuned loop)
*Broadband (unlike a tuned loop, excellent for AM DXing, SWL and Amateur)
*Portable (easy to walk with while directional noise finding or HF Fox Hunting)
Traditionally Flag antennas are large and designed for stationary use, but the idea for this antenna was to design a Portable Flag. It was designed to be the largest possible (to maximize gain) that would fit inside a car and it's still small enough to maintain a cardioid pattern up through 30 MHz. The portable Flag has an approximate dimension of 2 feet tall by 4 feet long which you (or a helper) can easily walk with while tracking down a signal. Unlike a tuned loop, the Portable Flag is a broadband antenna with unidirectional properties, and it's designed for direction finding from 1.8 to 30 MHz as long as an appropriate preamp is used. It's even useful for direction finding down in the AM broadcast band. The rear of the antenna produces a sharp null when pointed at the signal of interest and the sharp null is often used for direction finding versus using the broad peak which occurs when the front of the antenna is pointed at the signal of interest.
