Shakespeare Automatic Coaxial Switch Review

What Led Me to Try the Shakespeare Automatic Coaxial Switch

For years, managing radio setups has involved a delicate dance of cables and antennas, especially when juggling multiple radios on a single rig. The constant need to physically swap coax cables is not only inconvenient but can also introduce wear and tear on connectors. This is where the concept of an automatic switch for my amateur radio station became a compelling idea. My setup involves a primary HF rig and a secondary VHF/UHF rig that I often want to connect to a single, well-positioned outdoor antenna. The idea of an automated solution that handles this switching for me was incredibly appealing, promising a cleaner and more efficient station. I had been using a manual switch for a while, which worked, but it was far from ideal.

The Shakespeare Automatic Coaxial Switch caught my eye due to its promise of hands-free operation. My initial impression upon unboxing was positive; the unit felt solid, with a no-nonsense metal casing. The SO-239 connectors felt robust, and the overall build suggested it could withstand the rigors of a ham shack. I had briefly considered some other electronic antenna switch designs, but they often came with a much steeper price tag or more complex setup requirements. The simplicity and straightforward design of this particular switch were its main draw. My first reaction was one of hopeful anticipation – could this finally solve the cable-swapping headache?

Real-World Testing: Putting Shakespeare Automatic Coaxial Switch to the Test

First Use Experience

I installed the Shakespeare Automatic Coaxial Switch in my main ham shack, connecting it between my primary HF transceiver and a secondary all-mode VHF/UHF transceiver. The antenna feed point was on a single vertical antenna, known for its broadband performance across many bands. The test environment was my home radio shack, a controlled but busy space with multiple pieces of electronic equipment operating simultaneously. I tested its performance primarily by keying the microphone on each radio in turn, observing the automatic switching action. The switch performed its core function reliably, automatically selecting the active radio’s transmission path to the antenna without any manual intervention.

During this initial period, I subjected it to numerous short transmissions on both HF and VHF, as well as longer rag-chews. I also intentionally exposed it to the ambient dust common in my shack, though I avoided any direct water or extreme temperature exposure, as that falls outside its intended operational parameters. The ease of use was immediately apparent; once the cables were connected, it was essentially plug-and-play. The only minor surprise was how accustomed I quickly became to not having to reach for a manual switch, a testament to its seamless operation.

Extended Use & Reliability

After several months of consistent daily use, the Shakespeare Automatic Coaxial Switch has proven to be a dependable workhorse in my shack. It handles frequent switching between my two primary radios without any signs of faltering. I’ve made hundreds, if not thousands, of transmissions through it, and the SO-239 connectors show no noticeable wear or loss of conductivity. The unit itself remains securely mounted, and there are no loose parts or rattling sounds, indicating a solid build.

Maintenance has been minimal, primarily just keeping the connectors clean and ensuring cables are properly seated. The only real caution to note is that it’s an un-amplified passive device, meaning there’s no power consumption or complex circuitry to worry about failing. Compared to the manual switch I used previously, this automatic unit offers a significant upgrade in convenience and station tidiness. While more sophisticated, multi-radio, multi-antenna systems exist, for the specific task of managing two radios with one antenna, this Shakespeare model has held up admirably against more budget-friendly, less automated alternatives.

Breaking Down the Features of Shakespeare Automatic Coaxial Switch

Specifications

The Shakespeare Automatic Coaxial Switch, model AS-2, is designed to intelligently manage the antenna connection for two separate radio transceivers. Its core function is to automatically switch a single antenna between these two radios based on which radio is transmitting. This is achieved by detecting the RF signal when a microphone is keyed on one of the radios. The unit utilizes SO-239 connectors for all its radio and antenna connections, a ubiquitous standard in amateur radio that ensures broad compatibility with existing coaxial cables.

The switch maintains the antenna connection to the last transmitting radio until it detects a transmission from the other radio. This ‘lock-on’ feature prevents unnecessary switching during a conversation on one radio and only re-routes the antenna when a new transmission is initiated from the alternate device. This specification is crucial for maintaining signal integrity and avoiding the common annoyance of manually toggling between radios. Its passive nature means it draws no power itself, simplifying installation and eliminating a potential point of failure compared to powered antenna switches.

Performance & Functionality

In terms of its primary job, the Shakespeare Automatic Coaxial Switch performs exceptionally well. When one radio is keyed, the antenna is immediately directed to it, and this happens with a responsiveness that feels instantaneous to the user. The “lock-on” functionality works as advertised; the antenna stays with the transmitting radio until the other radio is keyed. This seamless transition is the key benefit of this device.

The main strength is undoubtedly its simplicity and effectiveness for its intended purpose. It does exactly what it says it will do, without fuss or complicated settings. There are no significant weaknesses in its core functionality, assuming it’s used within its specifications and with appropriately matched impedances. Its performance is consistent, and it handles the power levels typical for amateur radio transceivers without issue.

Design & Ergonomics

The design of this automatic switch is purely functional, prioritizing reliability and ease of integration into an existing radio setup. It features a sturdy metal enclosure that feels durable and capable of protecting the internal switching mechanism. The SO-239 connectors are well-mounted and provide a secure connection for coaxial cables.

While not aesthetically flashy, the unit’s design is straightforward and intuitive. There are no knobs, buttons, or user interfaces to navigate, making its setup and operation incredibly simple. You connect your two radios and your antenna, and it’s ready to go. This lack of complexity is a major ergonomic advantage, as it means no learning curve or potential for user error beyond correct cable connections.

Durability & Maintenance

Based on its construction and simple, passive design, the Shakespeare Automatic Coaxial Switch appears built for longevity. The metal casing and robust connectors suggest it can withstand regular use in a typical ham shack environment. As an unpowered device, there are no electronic components prone to failure over time.

Maintenance is practically non-existent beyond ensuring clean SO-239 connectors and properly tightened coax fittings. There are no internal parts that typically require lubrication or adjustment. Given its straightforward mechanical switching action, it’s reasonable to expect years of reliable service from this unit. Potential failure points would likely be related to mechanical wear on the internal switch contacts over extremely long periods of very heavy use, or damage from improper installation or physical impact.

Accessories and Customization Options

The Shakespeare Automatic Coaxial Switch comes with the unit itself and accompanying documentation, which typically consists of basic instructions for installation. There are no additional accessories included, such as specific lengths of coaxial cable or adapter fittings. The unit’s design is fixed, focusing on its core switching function with standard SO-239 connectors.

While the switch itself is not customizable, its use of standard SO-239 connectors means it is highly compatible with the vast array of coaxial cables and antenna systems available in the amateur radio market. This interoperability is its primary form of “customization” – it seamlessly integrates into almost any existing setup that uses this common connector type. There are no other radio inputs or antenna outputs, keeping it focused on its two-radio, one-antenna application.
