– Offers no performance advantage over the cheaper white model; the choice is purely aesthetic.

Best for: Hams who need the reliable, pre-tuned performance of the Tram 1477 but prefer a less conspicuous black finish for aesthetic reasons.

Expert Opinion: Functionally identical to the 1477, this version provides a great option for those trying to hide their antenna installation. It remains one of the most popular short-format best dual band 2m 70cm base antenna options on the market.

Comparison Insights on Best Dual Band 2M 70CM Base Antenna

When comparing these ten excellent dual band options, several patterns emerge that can guide your purchasing decision:

For those operating under strict height restrictions (HOA, urban location, attic install), the shorter antennas shine. The Diamond X30A and both Tram 1477/1477-B models, all around 4.5 feet, offer the best solution. They minimize visual impact while still providing usable gain (up to 6 dBd/dBi on 70cm).

If your primary goal is maximum range and high gain, look to the tallest models. The UAYESOK and YNIBST antennas both offer exceptional 8.5 dBi gain on 70cm and handle up to 200W, making them top performers for distant repeater work. However, they demand a more robust mounting solution due to their height (7 to 7.2 feet).

The middle ground, offering a great balance of size and performance, is held by the HYSHIKRA FB17UV and the Retevis options, both pushing 7.2 dBi gain in a manageable 5.5-foot package. These are ideal for suburban installations where you need reach but can’t install a massive antenna.

A critical consideration is installation complexity. Models like the Tram 1477 and Diamond X30A are pre-tuned and single-section, offering the easiest setup. Conversely, the TWAYRDIO Yagi requires careful directional alignment but delivers unmatched directional power for specialized communication links.

Finally, for turn-key value, the package that includes the low-loss coaxial cable (the Dual Band VHF UHF 2m 70cm Base Station Antenna package) provides a huge convenience, saving the buyer the trouble of sourcing and correctly connecting quality coax.

Final Verdict: Choosing Your Base Station Companion

Selecting the best dual band 2m 70cm base antenna depends entirely on your location and operational goals.

If you are a Beginner or prioritize Simplicity: Go with the Tram 1477 (or 1477-B). Its pre-tuned performance and compact size make setup quick, reliable, and frustration-free.

If you are an HOA Operator or restricted by height: The Diamond Antenna X30A is the premium choice for low-profile installation. Its DC grounding and reputation for superior build quality provide peace of mind in a small package.

If you need Maximum Reach and High Power: Choose the YNIBST or UAYESOK (both 8.5 dBi). These antennas are designed to maximize signal propagation, pushing your radio’s performance to the limit.

If you require Directional Performance (Satellite or Dedicated Link): The TWAYRDIO Yagi is the only choice. Its focused gain blows away omnidirectional antennas for specific point-to-point communication.

Frequently Asked Questions About Best Dual Band 2M 70CM Base Antenna

What is the difference between dBi and dBd gain figures?

Antenna gain is measured relative to a theoretical isotropic radiator (dBi) or a half-wave dipole (dBd). Since a dipole itself has 2.15 dBi of gain, the relationship is always dBi = dBd + 2.15. When comparing best dual band 2m 70cm base antenna models, it’s essential to check which reference point the manufacturer is using for an accurate comparison of actual performance.

Is a taller base antenna always better for signal reception?

Generally, yes. Taller antennas usually have higher gain because they use multiple stacked radiating elements (like the 7-foot UAYESOK antenna), focusing the signal closer to the horizon and increasing effective radiated power (ERP). Additionally, simply mounting any antenna higher off the ground improves line-of-sight and clearance from nearby obstructions.

Do fiberglass base antennas require an external ground plane or radials?

Many modern fiberglass base antennas, like the Dual Band Antenna with stainless steel radials, have an integrated ground plane. This usually consists of short metal radials included at the base to provide the necessary counterpoise. If your antenna is DC-grounded (like the Diamond X30A), it is internally protected against static buildup but still uses internal design elements to function efficiently without external grounding wires.

How important is the Maximum Power Input rating for a best dual band 2m 70cm base antenna?

The maximum power input indicates the most wattage the antenna can safely handle without being damaged (usually from excessive heat). If you run a standard mobile radio at 50 watts, a 100W rated antenna is sufficient. However, if you plan to use a linear amplifier or a high-power repeater (often 100W to 200W), choosing an antenna rated for 150W or 200W (like the YNIBST or HYSHIKRA models) is crucial for safety and longevity.

What should I check if my SWR is high after installing a pre-tuned antenna?

Even with a pre-tuned best dual band 2m 70cm base antenna, a high Standing Wave Ratio (SWR) often points to an issue external to the antenna. The three most common culprits are: a faulty or damaged coaxial cable, a bad connector (especially the PL-259), or mounting the antenna too close to a large metal object (like a chimney flashing or vent pipe) which de-tunes the antenna elements.

For VHF/UHF operation, should I choose omnidirectional or directional?

For general ham radio use, where you want to communicate with repeaters and other stations scattered around your location, an omnidirectional antenna (like the fiberglass sticks reviewed here) is necessary to provide 360-degree coverage. A directional antenna (Yagi) should only be chosen if you have a specific target (like a satellite or a distant, fixed repeater) that requires massive focused power in one primary direction.
