This page describes a homebrew 80/40 meter trap vertical antenna. Includes an interesting antenna raising system that allow easy setup and tuning.

The 30/40 meter **vertical antenna** project by IK4DCS details the construction of a shortened, self-supporting design, reaching a total length of 5 meters. The antenna incorporates a linear loading section and a coaxial cable trap for 30 meters, based on the "Antenne Volume 2°" text by Nerio Neri (page 223). The design uses six radials, three for each band, positioned at approximately 90° inclination and at least one meter above the roof or ground, connected via a 1:1 balun at the feed point. Mechanical construction utilizes aluminum tubing, with a 2.30-meter primary radiator section (30 mm diameter) joined to a second part using a Teflon insert and a PVC sleeve for rigidity. The linear load, approximately 3.70 meters long, accounts for a 30% physical shortening of the quarter-wave element. A capacitive load, made from three 50 cm radials, is integrated into the 40-meter top section for fine-tuning. Final adjustments involved radial inclination for 40 meters, as initial testing showed increased SWR and interference on 30 meters due to nearby resonant structures. The author emphasizes the importance of clear space for optimal performance and provides drawings and photos to clarify the build process.

The Radio Attic serves as a dedicated online marketplace for **antique radios**, offering a platform for enthusiasts to buy and sell vintage communication equipment. The site features classified advertisements, each displaying full-color photographs of the radio, a detailed description, and a direct link to the seller's email address. This structure facilitates direct communication between buyers and sellers, as transactions are handled independently, not by the webmaster. Listings are categorized by style, manufacturer, and year of manufacture, including models from Admiral, Airline, Atwater Kent, Crosley, Emerson, Fada, General Electric, Philco, RCA, Silvertone, and Zenith. The platform also tracks new additions, with 49 radios and 6 books added in the past 30 days, and highlights recently sold items, totaling 157 radios this year. Beyond sales, the site provides resources like a price guide and information on upcoming swap meets, such as the Southeastern Antique Radio Society's Spring Swap Meet in Forsyth County.

A 20 meter quarter wave vertical antenna by jerry sevick W2FMI QST Article

A **90-foot tall** top-loaded vertical antenna for the 160-meter band is detailed, constructed from aluminum irrigation tubing. The design incorporates four sets of four guy wires for structural stability, essential for an antenna of this physical size. This _monoband_ vertical is optimized for low-band operation, providing a robust solution for DXing and contesting on 1.8 MHz. The document includes specific construction methods for assembling the aluminum irrigation tubing sections and securing the guy wires. While a full NEC model is not explicitly provided, the physical dimensions and construction materials are sufficient for replication by experienced builders. The antenna's height and top-loading configuration are critical for achieving efficient radiation on 160 meters, particularly in minimizing ground losses.

Mobile vertical antenna for 144 MHz suitable for satellite signals reception by K5OE

Sharing beverage antennas with this switch boxes is possible. This article describes a 6-position remote antenna switch for Beverage antennas on 3 bands (160m, 80m, 40m). It allows selecting one of 6 antennas for each band without affecting other receivers. The system uses a control box with a rotary switch and a separate splitting box with bandpass filters for each band.

How to make a Weatherproof Vertically Polarised Omnidirectional Aerial, The Slim Jim Antenna

A simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres, made from 16 feet of RG58 coax cable. The performance is impressive for its size but not meant to replace a Yagi. The antenna features a tuning head, matching unit, tuning capacitors, band change switch, and matching transformer. The feedpoint is at the bottom of the loop. The document provides detailed instructions on assembly and operation.

The page contains the recommended Operating Code of Practice for 6 meters band as issued by UKSMG in collaboration with other organizations. It aims to improve productivity and enjoyment for all radio amateurs using the band. The code covers topics such as inter-regional calling frequency, local band plans, DX operations, and proper operating practices. It encourages adoption by other Amateur Radio Societies to promote responsible and respectful use of the 6m band.

W5ALT Indoor Vertical Antenna is a base loaded vertical antenna that can be tuned on almost all HF bands by adjusting a big coil. Operating a ham radio station from an apartment in Maracaibo, Venezuela, the author demonstrates effective communication with over 100 countries using a custom-built indoor vertical antenna. Addressing common misconceptions, the design uses a balanced approach with radials and a base-loaded vertical element made from affordable materials. The antenna fits discreetly indoors, covers 6 to 40 meter bands, and achieves acceptable SWR with an MFJ tuner. Despite limited space and typical apartment challenges, the setup enables reliable DX contacts, confirmed by numerous QSL cards, proving indoor antennas can perform well in constrained environments.
