UAYESOK Amateur Base Antenna Dual Band 2m/70cm 7.2ft Fiberglass Mobile Radio Antenna Vertical Base Station Antenna 5.5/8.5dBi So239 Connector for Repeater System Radio Scanner Vehicel Truck

The UAYESOK antenna is built for robust performance, featuring a 7.2-foot (2200mm) fiberglass structure and a high 200W power capacity. This high-performance model rivals commercial antennas by offering strong gain numbers—5.5dBi on VHF and an excellent 8.5dBi on UHF—ensuring maximum coverage. A key differentiator is the integrated ground plane (with three GP antennas), which provides superior anti-jamming capabilities and stabilizes the signal for both reception and transmission.

Key features that stand out:
– Integrated Ground Plane: Improves signal stability and anti-jamming performance.
– High Gain and High Power: Matches the YNIBST with 5.5/8.5 dBi gain and 200W capacity.
– Heavy-Duty Construction: Corrosion resistant and waterproof fiberglass built for challenging environments.

Pros:
– Excellent gain profile, especially on the 70cm band
– Direct grounded for lightning protection
– Strong anti-jamming capabilities thanks to the GP design
– Includes robust aluminum alloy mounting bracket and U-bolts

Cons:
– Installation requires managing a long (7.2ft) single section or multi-section assembly

Best for: High-performance base stations, repeater sites, and users operating in high RF noise environments who need signal stability.

Expert Opinion: The focus on an integrated ground plane separates this from some of the budget models. This feature is crucial for achieving truly stable, repeatable performance, especially if the antenna is mounted on a non-conductive surface like wood or fiberglass.

Comparison and Practical Insights

When trying to determine the best 2m/70cm base antenna for your needs, comparing specifications directly is useful, but real-world application matters more.

If height and size restrictions are your primary concern, the Diamond Antenna X30A and the Dual Band Antenna 2m 70cm GMRS are your best options. They stand at less than 5 feet tall, offering convenience while still delivering reliable local repeater access.

For those who prioritize maximum gain and range, you should look at the taller, multi-section designs. The YNIBST and the UAYESOK both offer impressive 8.5 dBi gain on 70cm and handle 200 watts. This high gain means a much flatter radiation pattern, crucial for long-distance terrestrial contacts.

When value and ease of use are key, the Tram 1477 (in white or black) is the clear winner. Its pre-tuned design means you spend zero time fiddling with SWR meters, and its 6 dBi UHF gain is plenty for most suburban operations.

Finally, consider power handling. While most modern mobile radios output 50 watts, if you plan on using an amplifier or operating a repeater, choosing a model like the 200W rated YNIBST or UAYESOK provides necessary overhead and peace of mind.

Making the Right Choice

Choosing the single “best 2m/70cm base antenna” truly depends on your specific operational environment:

If you live in an area with strict HOA rules or need a compact setup, the Diamond X30A offers the highest build quality in the shortest package. It’s expensive, but reliable.

If you require the absolute maximum signal strength for long-haul contacts, the YNIBST or the UAYESOK are tied for raw performance and high-wattage capacity. Look closely at the UAYESOK if signal stability from an integrated ground plane is important.

For the majority of ham operators seeking great performance on a reasonable budget, the Tram 1477 (or 1477-B) offers the most practical blend of moderate height, excellent gain, and unbeatable ease of installation. It’s the antenna I often recommend first.

Frequently Asked Questions About Best 2M/70CM Base Antenna

What is the difference between dBi and dBd when looking at antenna gain?

This is a common question when reviewing specifications. dBi (decibels relative to an isotropic radiator) measures gain compared to a theoretical antenna that radiates energy equally in all directions. dBd (decibels relative to a dipole) measures gain compared to a half-wave dipole antenna. Because a dipole itself has 2.15 dBi of gain, you can generally convert dBd to dBi by adding 2.15. When comparing different best 2m/70cm base antenna models, make sure you are comparing the same units (either all dBi or all dBd) for an accurate assessment.

Do I need to tune a pre-tuned dual-band antenna?

For high-quality, pre-tuned antennas like the Tram 1477 series, major tuning is generally unnecessary for the specific amateur bands (2m/70cm). They are factory-adjusted to achieve a low SWR (Standing Wave Ratio) across the primary frequencies. However, you should always check the SWR upon final installation using your own feedline and location, as environmental factors and nearby metal can slightly affect performance.

How does antenna height affect VHF/UHF performance?

Height is arguably the most important factor in VHF/UHF communication. Because 2m/70cm signals are mostly Line-of-Sight (LOS), getting your antenna as high as possible significantly extends your radio horizon. Even a moderately powerful antenna mounted 40 feet up will often outperform a high-gain antenna mounted only 15 feet up. Always prioritize a safe, high installation location.

What is the advantage of a DC Grounded antenna?

A DC grounded antenna means the radiating element is directly connected to the antenna mount for DC current. This provides two key benefits: it offers static dissipation (reducing background noise from atmospheric static) and it provides a path for lightning protection by shunting high-voltage static buildup to the ground system before it can damage your radio equipment. Many of the best 2m/70cm base antenna options, like the Diamond X30A, utilize this design.

What kind of feedline (coax) should I use with a 2m/70cm base antenna?

Signal loss (attenuation) is high on the 70cm band, especially over long distances. For runs under 50 feet, high-quality RG-8X might be acceptable, but for longer runs (50 feet or more), you should invest in low-loss cable like LMR-400 (or similar quality polyethylene foam dielectric coax). Using the right feedline ensures that the power leaving your radio actually reaches the antenna, maximizing the effectiveness of your best 2m/70cm base antenna.

Are these antennas also suitable for GMRS use?

Many dual-band amateur antennas are compatible with GMRS. The GMRS band (462-467 MHz) falls directly within the 70cm amateur band (440-450 MHz). Antennas with wide bandwidth, such as the Dual Band Antenna 2m 70cm GMRS reviewed here, are explicitly designed to cover both amateur and GMRS frequencies with a low SWR. Always check the antenna’s specific frequency range before purchase if GMRS is critical to your operation.
