remote antenna switching project by EI7BA

This Multiband Cubical Quad antenna a boomless Quad design with glass-fibre arms and a single coax wire connected to a remote antenna switch. This aerial work on 8 bands and has a 60-degree beam width. Despite achieving critical technical requirements, the antenna's three-dimensional structure presents obstacles, such as installation issues on fixed towers and risk of frost damage. The spider framework is built of stainless steel, with a compact 18-inch boom and strong angle iron arms. Tait use a variety of methods to fasten element wires and suggests placing them on the outside of the spreaders for improved insulation. The use of nylon twine or parachute cord between key attachment points allows for adjustable separation between pieces.

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.

A wifi remote antenna switch that can be controlled from a smartphone app

Optimizing the ZS6BKW antenna for full HF band coverage often requires specific modifications beyond its standard configuration. This resource details several enhancements, beginning with a simple series capacitor to improve 80m SWR, a technique W5DXP found effective for permanent installation due to its minimal impact on higher bands. Further improvements include a 10-inch parallel open stub for 10m resonance, shifting the frequency to 28.4 MHz with an SWR of approximately 1.8:1, a practical solution for Technician class operators. The document then explores a switchable matching section, adding or subtracting one foot of ladder line at the 1:1 choke-balun, which significantly impacts higher frequency bands and eliminates the need for a tuner on 17m. W5DXP's _AIM-4170D_ antenna analyzer measurements confirm these effects. More advanced modifications involve a parallel capacitor for further 80m SWR reduction, requiring remote switching for multi-band operation, and relay-switched parallel capacitors at specific points on the 450-ohm matching section to achieve low SWR on 60m, 30m, and 15m. These detailed steps, including _Smith chart_ analyses for the challenging bands, aim to transform the ZS6BKW into a truly all-HF-band antenna, reflecting W5DXP's practical experience in antenna tuning.

A project about reversible unidirectional Beverage antennas plus a remote switching system conveniently controlled by the operator

This article describes a simple yet effective multi-band vertical HF antenna design that performs exceptionally well across 80m to 10m bands. The antenna consists of a 13.4m wire mounted on a 12.4m Spiderpole, complemented by four 12m radials and a ground rod. Initially tuned with a manual LC circuit, it was later upgraded with a CG3000 remote auto ATU for convenient band switching. Despite antenna modeling software suggesting limited performance on higher frequencies, the system demonstrated excellent DX capabilities across all bands, outperforming more complex vertical antenna designs.

Building an automatic 8ch USB Relay switch using an existing Ameritron RCS-8V Remote Control Coax Switch and an externally mounted 5-way switch.

This is a remote antenna switch I use in my attic to connect transceivers in the basement to multiple antennas in the attic. The goal of this project is to be able to remotely connect one of the antennas in the attic to the only antenna cable available.

Review of the Ameritron 8 Antenna Remote Coax Switch with SO-239 connectors on 120V

The author describes building a remote switch box to control the direction of two reversible Beverage antennas. The switch uses a buried cable and relays to select the desired antenna direction from the shack. The design is simple and uses common components.

HamParts produces and sell remote control accessories for ham radio operators, including antenna switch controllers and stack match controllers. Remotius 64, K9AY/4-WAY Antenna Switch Controller Easy Controller series, Lora devices, and many more ham shack accessories.

SO2R Focus Control and SO2R FC Server are freeware VB6-based tools enabling remote or local control of modern SO2R controllers (supporting OTRSP and MK2R protocols) outside contest logging sessions. The client (SO2R Focus Control) manages serial-connected controllers and can interface remotely via LAN or internet using the optional SO2R FC Server, which supports up to two concurrent clients. Key features include AUX port control with customizable labels, interlock options, AES-256 encrypted network communication, and compatibility from Windows XP through Windows 11. Designed for operators needing flexible station control—especially for remote antenna switching—both programs install cleanly via NSIS and uninstall completely.
