Operating on the HF bands, Kenwood's TS-990S and TS-890S transceivers represent their flagship offerings, providing advanced features for DXing and contesting. My personal experience with Kenwood gear, particularly the TS-590SG, confirms their reputation for solid receive performance and clean transmit audio, often noted in pileups. The TS-590SG, a popular choice for many hams, delivers reliable performance across the HF and 6-meter bands, making it a versatile station centerpiece. For VHF/UHF enthusiasts, the TH-D75A tribander offers 144, 220, and 430 MHz capabilities in a portable form factor. This handheld unit integrates D-STAR and APRS functionalities, appealing to operators who value digital modes and location-based services on the go. The inclusion of 220 MHz, a less common but valuable band, expands its utility for regional communications and specialized nets. Kenwood's enduring presence in the amateur radio market, dating back to 1955, underscores a commitment to quality and innovation. Their product range, from high-end base stations to feature-rich portables, continues to support a wide array of operating styles and technical requirements within the ham community.

The 1/4 wavelength vertical antenna project, initially designed for 20 meters, has evolved into a versatile portable solution covering 10 through 60 meters. K0BXB details its construction, emphasizing a bottom-loaded design with a tapped loading coil and four 10-foot counterpoise wires. The author shares personal experiences and field results, including **18 QSOs** during a park activation on 17m and 30m with 10 watts, and a **2,435-mile** contact with a contest station in Bonaire on 20m using 5 watts. Comparisons are drawn to commercial offerings like the _Wolf River Coils TIA_ and _QRPGuys Triband Vertical_, highlighting the DIY antenna's small footprint, light weight, and ease of tuning for POTA activations. The resource includes insights into using test equipment such as the _NanoVNA_ for SWR optimization and discusses various radiator lengths, from 17-foot wire to a 102-inch whip, demonstrating adaptability for different portable setups. Construction tips cover coil winding, tap placement, and connecting feedlines and radials using common components.
