Commerical user's in EU were next. Spread to NA in the mid 90's. No, was not originated by the German military, type C was used by the military. Type 7-16 was developed and used for commercial broadcast, before it was 6-16 (60 Ohms) > > What improvements does it have over the N? ### 2900 v rms vs 500 vrms. Good to 6 Ghz. Handles 20 kw pep on hf bands. Not much bigger than a typeN /so-239. 1.25" square vs 1" square for a female chassis connector. No, 7-16 is specified 7.5KW at 30MHz. N is rated 1KV working voltage, 7-16 is rated 2.7KV ## BTW, that '10kw PEAK' rating for a type N is PEAK... which is DOUBLE PEP /RMS ! A 100 w light bulb is 200 w PEAK. 120 vac = 170 v PEAK. Peak V / fixed resistance = PEAK current. Peak current x Peak Voltage = Peak power. There is nothing like "peak power". A rating "peak" for power does not exist. Type N is specified 1.8KW at 30MHz. ## Ur 1.5 kw pep out linear actually puts out...'3 kw PEAK' Peak power is a bs rating... if u see it being used... divide by two, to get the real rating. No, 1.5KW pep output are not 3KW peak. It is 1.5KW RMS, measured at the crest of the modulation envelope 73 Peter _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
