One of my towers is 270 feet from the entry point (where all the switching and grounding takes place) to the house. I have a 200 foot length of LMR600 (loss of 0.42 db per 100ft @ 30 mhz) and lots of
Well, lets see: 2.16 dB loss => 60.8% power delivered to load 1.40 dB loss => 72.4% power delivered to load assuming 1500 watts in, the difference is 174 watts. Look at it this way, if you use the lo
Look at it as less than 1 dB difference. That's 1/6 of an S-unit, which is insignificant. The 270 ft of Belden is "better" since you avoid additional connectors and their additional loss and failure
I couldn't disagree more. Three quarters of a dB is not to be treated so lightly, not in a station where all the easy/cheap dB have already been gained. I'm sure Bruce can handle the waterproofing of
If it were my station the answer would depend a LOT on if this was a 10 meter run or a 160 meter run - many people feel the UHF barrel connector and two PL259s are visible to the RF - more on 10M tha
Bruce, The difference neglecting the additional connector losses is 0.76 dB. At 1500 watts, the difference in power delivered would be 174 watts. The losses associated with the additional splice will
and db Jeez - they sure must've screwed up the installation of the PL259's. "Feel" and "claim" are not acceptable measurements. A couple of EE undergrads (who happen to belong to TT occasionally) som
It's easy to put such claims to a "smell test". 1-2dB loss and 1500 watts the power loss would be between 150 and 350 watts in the connector. A reasonable test would be to run 500-1500 watts for a f
1-2dB ~~ Holy CRap Batman. I guess my TH6DXX esentially is a dipole on 10m then as I have several barrels and pl-259's in line. Where do people get this stuff? Their wives? TIC, don't get excited....
