A Multiband Slinky Coil for the PAC-12 portable Antenna, can be used also as a dual PAC-12 dipole by James Bennett

A dual band vertical antenna for 160 and 80 meters band, on a 18m spiderbeam fiberglass pole. This vertical is a good compromise when you want good performance on these two low ham bands and don't have the space to install two seperate antennas.

A dual band 40-80 vertical antenna on an 18m Spiderbeam Fiberglass Spiderpole, with monoband performance

This article describes the construction of a simple dual-band VHF/UHF end-fed vertical dipole antenna designed for local repeater access using an Icom IC-705 radio. Built from a single piece of RG58U coaxial cable, the antenna consists of a 460mm exposed inner conductor, 450mm of intact coax, and a 9-turn choke balun wound on a 27mm former. Mounted on a 10m Spiderpole, the antenna achieves excellent SWR readings (<1.2:1 on 2m, <1.5:1 on 70cm) and provides effective coverage of local repeaters with unexpected reach into distant locations.

This project outlines a simple, cost-effective 40m band HF dipole antenna design, ideal for beginners. Constructed with insulated copper wire and a 1:1 balun, it offers a 50-ohm impedance, suitable for both 40m and 15m bands due to the harmonic relationship. Calculations account for a K factor, ensuring optimal length and performance. Antenna modeling with 4NEC2 confirms practical access to both bands, though real-world results may vary. Lightweight materials and straightforward assembly make it an accessible and versatile amateur radio solution.
