When the world feels just one call away…

The Momobeam TRI16BT is more than an antenna — it is the beam built for those who live for rare DX, pileups, and contest adrenaline. Big tower presence, massive forward gain, and the confidence of hearing what others miss.

Because some stations don’t just operate… they dominate.

Mutual Coupling Between HF Antennas: What You Need to Know

🚨 HF Operators, Take Note!

If you’ve got multiple HF antennas close together, your signal might be “off” without you knowing why. The culprit? Mutual coupling—when antennas interact and affect each other’s performance.

What can happen:

⚡ Resonance shifts → unstable SWR

🔌 Impedance changes → harder to match

📡 Distorted radiation patterns → unwanted lobes

📻 Unwanted RF in nearby receivers

How to fix it:

📏 Keep distance : ideally ≥ 0.25 λ and orient antennas orthogonally

🛠 Electrical decoupling: RF chokes, proper baluns, use of high quality coaxial cables.

✅ Takeaway: Mutual coupling happens—but with the right setup, your HF station will stay steady, predictable, and perform at its best.

Oggi per me qualche ora di attività in HF dopo molto tempo, attivati i 15 metri SSB per il Contest IARU dalla postazione di II9K con il nominativo II9HQ. Grazie a Giuseppe Spanò per aver condiviso con me il suo setup.
