Can anyone suggest where I might find a table which describes the POWER handling capability of the various coax cables we use in amateur radio? Thank you for your interest. Dave, WT8R -- FAQ on WWW:
I have never seen such a thing. The big variable is duty-cycle. For example, RG-213/u typically runs comfortably warm with 15k on 14MHz using unprocessed SSB-Voice. However, switch to RTTY, and 15k
Try at The RF Connection, he has tables for both power and attenuation. http://www.therfc.com http://www.therfc.com/powerrat.htm http://www.therfc.com/attenrat.htm 73 Warren - K2BM -- FAQ on WWW: htt
I have to agree with Rich here. In the CB Radio shootout scene, typical 10 second keydowns I have repeatedly put a 3CX3000 run WAY over ratings into 213... Typical about 18Kw (high plate volts, and W
I agree with you on this, Rich. Sure there is a "maximum power handling" capability and that may be specified usually as a CW rating. IMHO, one of the real numbers you need to look for is voltage bre
What good is a CW rating if the seeker of info only uses SSB? - Rich..., 805.386.3734, www.vcnet.com/measures. end -- FAQ on WWW: http://www.contesting.com/ampsfaq.html Submissions: amps@contesting.

output, You are probabably OK. One thing where you need to be careful though with RF voltages is that you need to look at the peak voltage instead of just the RMS voltages. The 194 volts you give is
Okay...it seems nobody buys ARRL handbooks anymore! There are different kinds of RG-58 and RG-59. TMS RG-58C is only good for 300 v rms, while Belden RG-58C (8262) is good for 1400 v rms. Plain old R
ambient. Phil, Answer this question please. At 1500 Watts, your RMS RF voltage is 273.86 Volts. So why do you say that RG-58 is only good for 350 Watts. Even the crappy stuff you mention is capable
years ago i made a note of the rg-58u ratings from the AMPHENOL CATALOG cw x4 for ssb. the rating for 75 mtrs was 2.6 kw which would be a round 7 amps.?? the 20 mtr. rating was .8 kw continous. the c
Don't ask me...this is the MANUFACTURER'S rating for 30 mhz! For the same reason your wife's hair dryer is not wired with a #22 AWG cord. Plus 1500 watts is 5 times what the manufacrurer rates the c
