In terms of construction you can apply the same shape as that of the Cobwebb, the multiband antenna that follows the same construction principle. Using PVC cement, add 7' lengths of the half-inch thin-wall PVC to each coupler end. The name of the game with antennas is not resistance but impedance. That is especially useful if you are restricted to certain HF bands due to your license. That is just 1.1 dB less than a regular half wave dipole when you compare it to the side of the half wave dipole where it radiates at max, perpendicular to the radiator. But with 7m to 8m wide, theyre still large for a small roof or garden. I found that the Halo was a fraction better than the vertical in terms of reception. on 10 meters (some people miss this part). Building an effective HF antenna can be difficult when space is limited, building a beam antenna may appear impossible ifyou don't have enoughroom to house the directors and With this arrangement, the However, if only three bands are desired or five bands, the same approach would apply for the bands you want to equip.
