Antenna Color Customization: Why You Should Never Do It Yourself
⚠️ DO NOT CHANGE ANY PART OF THE ANTENNA WITHOUT ADVISING FT-RF
Military-grade antennas are built to strict specifications. Unauthorized modifications may cause operational failure or equipment damage.
FT-RF frequently receives inquiries about repainting military vehicle antennas. While we understand the need, we must emphasize: never change the antenna's color or any part without consulting us.
This article explains the risks and the correct way to proceed.
1. Built to Precise Specifications
Our MJ-Series antennas are engineered to meet strict standards for frequency response, mechanical strength, environmental resistance, and electromagnetic compatibility. Every component—including the paint—is part of a complete system. Changing any element can alter performance or mechanical integrity.
2. The Hidden Danger: Heat + Glue = Water Damage
Critical housing and connector interfaces are sealed with industrial adhesives. However, no standard adhesive withstands high temperatures indefinitely:
🔥 At 120°C (248°F), conventional adhesives degrade within 5 minutes.
Once glue becomes brittle:
- Seals break down → moisture enters
- Water ingress causes: detuning, corrosion, short circuits, or complete failure
Key point: Most spray paints require baking above 120°C. A "simple" paint job can destroy adhesive seals—and your antenna's waterproof rating—in minutes.
3. More Risks of Unauthorized Modifications
| Risk | Consequence |
|---|---|
| Paint thickness | Alters resonant frequency |
| Conductive/metallic paint | Detunes the radiating element |
| Overspray on connectors | Affects grounding |
| Chemical solvents | Attack plastic/rubber components |
| Unauthorized work | Voids the product warranty |
4. The Right Way: Contact FT-RF First
✅ Step 1: Contact us with your model number, current color, desired color (RAL/Pantone), and use environment.
✅ Step 2: Our engineers evaluate feasibility—paint compatibility, adhesive tolerance, and structural integrity.
✅ Step 3: Choose your solution:
| Option | Description | Best For |
|---|---|---|
| Factory repainting | Controlled coating at our facility | Guaranteed waterproofing & performance |
| High-temp adhesive upgrade | Replace with heat-resistant glue | Field customization or third-party painting |
✅ Step 4: Receive updated test reports, a new product label, and continued warranty coverage.
5. FAQs
Q1: Can I use automotive touch-up paint?
No. Even small areas affect performance. Contact us for a repair kit.
Q2: What if I only paint the mounting bracket?
Generally acceptable, but consult us to avoid accidental overspray.
Q3: Does high-temp adhesive cost extra?
Yes, but far less than replacing a water-damaged antenna.
Q4: How long does factory repainting take?
Typically 5–7 business days. Expedited service available.
6. Conclusion
⚠️ One wrong paint job can turn a reliable antenna into a field failure.
FT-RF helps you achieve the look you need—without compromising performance.
