If you’ve recently started your journey into Amateur Radio, you’ve probably noticed one thing very quickly: cables are everywhere. Between your HF rig, your dual-band mobile, and your various antennas, the back of your desk can start to look like a bowl of spaghetti.
At Tecomart, we believe your radio experience should be about making contacts, not swapping cables. That’s where the Diamond Antenna series comes in.
What Is a Duplexer or Triplexer? (The Beginner’s Guide)
Think of these as smart traffic controllers for your radio signals.- Duplexer (like the MX-62): Lets you use two different frequency ranges (for example, HF and UHF) on a single cable.
- Triplexer (like the MX-2000): Allows three different frequency ranges to share one antenna or cable.
Diamond Antenna is world-renowned for making low-loss components, meaning they don’t weaken your signal as it passes through.
Finding the Right Match at Tecomart
1. The Standard Duplexers: MX-62 & MX-72 Series
These are perfect for hams running a standard HF + VHF/UHF setup.- MX-62M / MX-62N: Robust and powerful, handling up to 600W (PEP). If you use N-Type connectors for your UHF gear, the MX-62N is the best option for a cleaner signal.
- MX-72 Series (A, D, H, N): Ultra-compact units offering up to 60dB isolation, ensuring that transmitting on one band does not interfere with another radio.
2. The Powerhouse Triplexers: MX-2000 & MX-3000
For operators who want maximum flexibility, a triplexer is a major station upgrade.- MX-2000 / MX-2000N: Supports 6m, 2m, and 70cm (HF/50/144/430MHz) through a single feed line, with power handling up to 800W.
- MX-3000 / MX-3300: Designed for advanced operators, including support for the 1200MHz (23cm) band. These models use LPF/BPF/HPF filtering to keep signals cleanly separated.
3. For the Listeners: SS500 Splitter
If you are a Shortwave Listener (SWL) or scanner user, the SS500 is a wideband splitter (0.5–500MHz) that allows two receivers to share one antenna without noticeable signal loss.
MX3300MN: HF 144/430/1200MHz
Which Connector Do I Need?
Tecomart stocks multiple connector configurations to match existing equipment:- M-P (PL-259): Standard for most HF and VHF radios.
- N-P (N-Type): Preferred for UHF and 1200MHz operation due to significantly lower signal loss at higher frequencies.
Splitter/Combiner for Recieving : SS500: 0.5 to 500MHz
Comparison Table
| Model | Type | Bands Supported | Max Power |
|---|---|---|---|
| MX-62M | Duplexer | HF/6m + VHF/UHF | 600W |
| MX-72N | Duplexer | HF/VHF + UHF | 1000W (HF) |
| MX-2000N | Triplexer | 6m + 2m + 70cm | 800W |
| MX-3000N | Triplexer | 2m + 70cm + 23cm | 800W |
| SS500 | Splitter | 0.5–500MHz | Receiving Only |
Why Buy Diamond Antenna Products from Tecomart?
A poorly made duplexer or triplexer can cause high VSWR, potentially damaging expensive final transistors in your radio. Diamond Antenna products are known for:- Minimal Loss: Less than 0.2dB in most models.
- Built to Last: High-quality 5D-2VS coaxial tails and heavy-duty shielding.
- Tecomart Support: Expert guidance to help you choose the right model.
