I have never had a problem with soldering PL-259’s and I have been putting them on since 1959! I know how to soldering them correctly. Sent from my iPhone > On Dec 8, 2018, at 2:57 PM, Richard (Rick) Karlquist > wrote: > > > >> On 12/8/2018 11:34 AM, terry burge wrote: >> Thanks John,

Thanks to all who took the time to reply to my email and those who offered me direct assistance. I have found a 3 element triangle array from Hi-z from a fellow YCCC member so I got lucky. Now to install it and see how it works! Thanks 73, Steve Jobes W1dxh Sent from my iPhone

Now that the leaves are off the trees and the cold weather has returned it's time to do antenna work. I have an inverted L between two trees with 34 radials on the ground. Four radials are 135 feet long, the rest 70 feed long. I choose these lengths because they fit my yard. During the summer

Hi Jim, A 13-30 DIN connector is like a flange connector used with high power transmitters (e.g., television transmitters and 50 KW AM), but it uses threads rather than a flange. 73 Frank W3LPL - Original Message - From: "Jim Thomson" To: "TopBand List" Sent: Saturday,

Hi Paul, I'm only the messenger! I'm very suspicious of that NOAA forecast, although its disappointing that there is scant evidence of Cycle 25 activity other than occasional very weak, tiny, very short lived opposite polarity sunspots. The future isn't what it used to be! 73 Frank

And that's how PL259's should be installed...excellent. Do that and you won't have problems with them. They're great connectors if installed correctly. Most don't... I have no argument for a Type N over a propery installed PL259 on braided cables.. A high wattage iron is important. Want

Since you asked. In my antenna system I have about 500 PL-259 connectors. 99% of them are King Silver Teflon connectors. I built the system in 1988 and 1989. So almost all of it is 30 years old. To Date I have had three failures all due to water getting into the connectors cable and one rusted

>>W6NL asked me this question - would you run 1500 watts with BNC connectors? It depends on the duty cycle, length of transmission and vswr. Brief contester type transmissons at 50% d/c into a load with Z = line characteristic Z is probably okay. AM broadcasting 1 KW carrier for 24 hours
