Comparison Insights and Buying Advice

Selecting the right antenna depends on balancing three factors: size, gain, and budget.

For operators living in areas with height restrictions or needing a stealth installation, the Diamond X30A and the HYS TC-40UV are the top picks due to their short stature, though you sacrifice some long-range capability. If you need a quick, affordable performance boost, the Tram 1477 or 1477-B provides exceptional value and impressive pre-tuned gain for its price point.

When maximizing range is the goal, you should focus on the antennas with the highest gain figures. The YNIBST and UAYESOK are standouts, both pushing 8.5 dBi on the 70cm band and handling a robust 200W. Their length is significant, but the increase in repeater coverage and clarity is undeniable.

Finally, while most antennas reviewed here are omnidirectional, the TWAYRDIO Yagi is the only exception. If your goal is to hit one specific distant target or engage in VHF/UHF satellite communication, the Yagi’s 11.5 dBi directional gain will dramatically outperform any omni antenna. Beginners should strongly consider the Dual Band VHF UHF bundle as it provides crucial components like the coax cable and adapters, simplifying the initial setup process dramatically.

Final Verdict: Which Base Antenna Wins?

If you’re asking which model is truly the best 2m 70cm base antenna for most hams, the answer is often found in balancing high performance with practicality.

🥇 The All-Around High-Performer: The YNIBST 2m/70cm Dual-Band Base Station Antenna takes the top spot for serious fixed base use. Its 200W power rating and outstanding 8.5dBi UHF gain make it an absolute workhorse, future-proofing your station for years to come.

🥈 Best Value and Ease of Use: We highly recommend the Tram 1477/1477-B. It delivers exceptional gain figures for a single-section antenna and the pre-tuned, hassle-free setup is invaluable for maximizing your time on the air.

🥉 Best for Stealth/Urban Areas: The Diamond Antenna X30A remains the king of reliable, compact dual-band operation. It’s short, tough, DC-grounded, and performs flawlessly where larger antennas are impractical.

Common Questions About best 2m 70cm base antenna

How high should I mount my dual-band base antenna for optimal height?

Generally, the higher the better, especially for VHF/UHF frequencies which operate line-of-sight. The optimal height is one that provides a clear view over surrounding obstacles like trees and neighboring houses. Mounting your antenna on a mast at least 20 to 30 feet high will significantly increase your coverage and ability to hit distant repeaters compared to mounting it low on the roof or in an attic.

Are fiberglass base antennas durable enough for heavy weather?

Yes, absolutely. The fiberglass construction seen in most best 2m 70cm base antenna models (like the Diamond X30A, Tram series, and YNIBST) is highly corrosion-resistant and waterproof. The fiberglass shields the internal radiating elements from ice, UV exposure, and wind. Always check the antenna’s specified wind rating, as taller, multi-section models require stronger mounting infrastructure.

Do I need to tune or adjust these 2m 70cm antennas?

Most modern dual-band base antennas, especially those specified as “pre-tuned” (like the Tram 1477), are factory-adjusted for low VSWR across the ham bands and require no cutting or tuning. For models that are assembled from multiple sections (like the YNIBST or UAYESOK), proper assembly according to the manual is critical to achieve the low SWR and high gain specifications.

Can I use these high gain antennas for GMRS as well?

Yes, many of these dual-band antennas cover the GMRS frequency range (around 462-467 MHz), which falls within the common 70cm (UHF) operating range (400-470 MHz). The Dual Band Antenna 2m 70cm GMRS model explicitly lists GMRS compatibility. Always confirm the antenna’s full frequency range specifications to ensure it covers your specific GMRS channels efficiently.

What is the advantage of an integrated ground plane design?

Antennas with an integrated ground plane (like the UAYESOK) often exhibit stronger anti-jamming characteristics. While the fiberglass enclosure provides physical protection, the ground plane helps establish a solid RF ground counterpoise, which improves the antenna’s radiation pattern stability and enhances the quality of both reception and transmission.

Should my best 2m 70cm base antenna be grounded for lightning protection?

Yes, grounding is essential. Base station antennas should always be grounded according to local electrical codes. Some antennas, like the Diamond X30A, are internally DC grounded, meaning the antenna itself appears as a short circuit to DC and can shunt static buildup. However, this DC grounding is usually not sufficient to handle a direct lightning strike, so external grounding rods and lightning arrestors on the coaxial cable are mandatory safety components.
