COAXIAL CABLE
1.General applications and Functions
TA HENG coaxial cables are designed for providing the excelle properties of high band width, low signal attenuation, and prevent signal leakage or interference in signal transmission industry.
The typical application of TA HENG coaxial cables include radio, television, audio/video appliance, computer, radar, satellite antenna TV, community antenna TV, master antenna TV. closed-circuit TV, home entertainments, and widespread use in local area networks (LANS), instrumental control systems, detector area, etc.
In order to insure consistent cable performance and uniform electric properties TA HENG had introduced the precise quality control testing and electrical inspection to check every critical property － impedance, capacitance, voltage, attenuation，physical characteristics，elongation, flame retardancy , both on line and in the lab to comply with MIL specifications and customer's requirements.
2．Reference application based on the relationship of coaxial cable and characteristic impedance
| Characteristic impedance Ω | Typical Application |
| 50 | Radio |
| 75 | TV |
| 95 | Computer |
| 125 | Specialty |

4.化學發泡與物理(氮氣)發泡之切片比較
放大倍數：50倍 (10X目鏡+5X物鏡)
• Foamed
• 氣泡顆粒大小不一，且較不均勻
• 氣孔過大部份會影響其特性表現
• 衰減偏大，迴饋損失偏小，駐波比偏大
• Skin-Foamed-Skin
• 氣泡顆粒大小一致，分佈均勻
• 洩漏電流較小，可改善化學發泡之缺點
• 衰減偏小，駐波比偏小
