Frequently Asked Questions (FAQs)

1. Which coaxial cable has the least amount of signal loss?

For long cable runs (100 feet+), using Cable Type 400 or even better Cable Type 600 Low Loss Coaxial Cable is best for least amount of signal loss due to cabling.

2. What is a low loss coaxial cable?

What is a “Low Loss” Coaxial Cable? As the name implies, Low loss coax will deliver a lower attenuation when applied as a replacement for similar diameter RG cables used in very same wireless applications. They offer a lower overall attenuation due to several key factors: Solid inner conductor.

3. How long can a coax cable be before signal loss?

The longer the coax run, the more loss and the more expensive it gets. The signal arriving at the receiver from anything longer than 100 feet of RG8X is probably going to cause trouble. Runs over 200 feet without amplification are only a dim possibility.

4. Is RG58 low loss?

Braided CablesRG 58 FME Xtra Low Loss-Cables Procom-designs having the lowest loss possible for RG 58-type coaxial cable: (below 0.3 dB per m at 900 MHz) and a very precise 50 Ω characteristic impedance. The cables are produced under continuous automatic control to ensure the high quality.
