Frequently Asked Questions (FAQ)
1. How does your 1-1/4″ coaxial cable compare to a Hansen cable?
Our 1-1/4″ coaxial cable is manufactured to strict ISO 9001:2015 quality management standards, making it a direct, high-performance equivalent to a Hansen cable. It features the same structural integrity, including an annular corrugated copper outer conductor , ensuring exceptional shielding attenuation (≥ 120 dB) and ultra-low PIM at a highly competitive value.
2. Where is an RF coaxial cable of this size typically deployed?
Because of its large diameter and massive 310 kW peak power rating, this 1-1/4″ coaxial cable is primarily used as the main feeder line in macro cell towers (BTS) and large-scale in-building distributed antenna systems (DAS). It is ideal for long vertical or horizontal runs where minimizing signal attenuation is the top priority.
3. What are the most important coaxial cable specifications for evaluating signal loss?
When reviewing coaxial cable specifications, you should look closely at the attenuation table. For example, our 1-1/4″ cable boasts an incredibly low attenuation of just 2.67 dB/100m at 800MHz and 4.28 dB/100m at 1800MHz. This ensures that your RF coaxial cable delivers maximum signal strength from the base station directly to your antennas.
