לפני כמה ימים שאלתי משהו דומה אני רציתי להישתמש בכבל מסוג rg142 במקום rg58 הנה מפרט של כמה סוגי כבלים וההנחתה שלהם אני מצרף תמונה שם רשום גם כמה הנחתה תהיה בסוגי התדרים
Technical specifications for RG178/U TEFLON brown Diameter 2 mm, our tiniest cable dB loss/100m @ 100MHz ~25dB Suitable for very short runs (1m-2m) and not more than 100W power Very suitable for internal interconnection due to heat resistance, virtually impossible to burn isolation while soldering, also suitable for wilkinson combiners and wideband transformers. Technical specifications for RG174 Diameter 2.8 mm dB loss/100m @ 100MHz 30dB Suitable for very short runs (1m-2m) and not more than 40W power Maximum recommended power handling 40W Technical specifications for RG58C/U Diameter 4.95 mm dB loss/100m @ 100MHz 15.3dB Suitable for short cable runs, up to 5m Maximum recommended power handling 100W Technical specifications for RG213U Diameter 9.5 mm Velocity factor 66% dB loss/100m @ 100MHz 7.8dB Suitable for medium cable runs, up to 10-15m Maximum recommended power handling 1000W Technical specifications for Belden H155 Diameter 5.4 mm Velocity factor 79% dB loss/100m @ 100MHz 9.3dB Suitable for short cable runs, up to 5-10m Maximum recommended power handling 150W Technical specifications for Belden H500 Diameter 9.8 mm Velocity factor 81% dB loss/100m @ 100MHz 4.6dB Suitable for longer cable runs, up to 20-30m Maximum recommended power handling 1200W Technical specifications for RG142/U high temperature teflon Dual silver shields. Brown tinted FEP jacked Diameter 4.9 mm Velocity factor 70.9% dB loss/100m @ 100MHz 5.5dB Suitable for longer cable runs, up to 20-30m Maximum recommended power handling 1300W This is the best cable for Wilkinson combiners, internal wiring and all applications which require direct soldering, good power handling and high temperature resistance. This is the cable to use for internal wiring in high power amplifiers (more than 300W).
