Tram 1191 50-Watt Pretuned Dual-Band Kit
The Tram 1191 is a pretuned dual-band antenna designed for 144-148 MHz and 440-450 MHz operation, with a 2.5 dBd gain on the 2-meter band and 4.5 dBd gain on the 70-centimeter band. It is built for up to 50 watts of max power, providing robust performance for many mobile radio setups. The glass-mount design aims for quick, clean installations on glass surfaces, reducing the need for dedicated mounting hardware. Expect straightforward tuning out of the box and solid on-vehicle performance for VHF/UHF communications.
HYS UHF/VHF 2m/70cm NMO Antenna with Glass Mount
This HYS antenna covers 136-174 MHz and 400-470 MHz with a maximum input power of 100 watts and a gain of 2.15 dBi (2m) / 0 dBi (general reference). The 21-inch fiberglass body is paired with an NMO connector and a 13-foot RG58 coax, plus a PL259 connector. The included L-shaped Fender Mount facilitates installation on vehicles where a glass mount may not be ideal. It offers a reliable option for mobile operations requiring broader band coverage with a simple mounting approach.
Tram 1192 50-Watt Pretuned Dual-Band Kit
The Tram 1192 series extends the glass-mount concept to a similar dual-band range (150-154 MHz and 450-470 MHz) with a 2.5 dBd gain on the 2-meter band and 4.5 dBd on the 70-centimeter band. It is pretuned for quick setup and typically provides a compact, sleek installation suitable for vehicles prioritizing aerodynamic profiles. As with other glass-mount designs, placement and window tint considerations can influence performance, so aim for clean lines and minimal obstruction inside the vehicle.
Larsen Glass-Mount Antenna Bundle
The Larsen glass-mount bundle focuses on a 2m/70cm configuration and includes a compact glass-mount antenna paired with a pocket reference card bundle for quick field access to essential radio information. This option is suitable for operators who value portability and quick setup, with the Larsen brand known for durable, corrosion-resistant elements. Consider the mounting surface and glass type, as these can affect mounting stability and performance over time.
HYS Amateur Dual-Band Magnetic Base Antenna
HYS offers a dual-band magnetic base antenna designed for VHF and UHF applications on 2m/70cm bands, with a 17.12 inch stainless steel mast and a 3.5 inch magnetic base. It supports 136-174 MHz and 400-470 MHz ranges, delivering 50 watts of maximum input power with gains around 2.15 dBi (2m) to 3.5 dBi in some configurations. The magnetic base provides easy, no-drill mounting on metal surfaces, making it a flexible option for temporary or semi-permanent installations. Ensure a proper metal ground plane for best results.
Buying Guide: Key Purchase Considerations
- Frequency Coverage: Identify the bands you need (2m, 70cm, or both). Pretuned dual-band antennas simplify installation but verify exact frequency ranges match your equipment and local regulations.
- Mount Type and Surface: Glass-mount antennas offer quick installs on vehicle windows but may be sensitive to tint, temperature, and vibration. NMO and magnetic-base options provide different mounting flexibility; consider your vehicle type and preferred permanence.
- Power Handling: Match antenna power ratings with your radio amplifier or transceiver’s output. Higher power handling can improve reliability under dense propagation, but many mobile installations work well within 25–50 watts.
- Antenna Gain: Balanced gain on each band influences signal strength and receiving sensitivity. Dual-band designs typically trade a bit of gain on one band for broader coverage on the other.
- Physical Length and Aerodynamics: Longer antennas offer greater efficiency but can affect vehicle aesthetics and clearance. Glass-mount antennas often maintain a lower profile, while some 2m/70cm models extend taller than a typical windshield.
- Installation Accessories: Check included mounting hardware, coax length, and connectors. Some kits come with L-mounts, ground-plane requirements, or specific coax types; confirm compatibility with your radio and vehicle.
- Durability and Weather Resistance: Look for weather-sealed housings and corrosion-resistant materials, especially for vehicles exposed to humidity, road salt, or sun exposure.
- Brand Reputation and Support: Reputable brands offer documentation, compatibility notes, and after-sale support that can simplify troubleshooting or upgrades.
When evaluating options, align product features with your typical operating environment—city commutes, long highway runs, or off-road use—and consider how each mounting method affects installation time, vehicle aesthetics, and maintenance needs.
