I put resistors (always 100k or more) across EVERY feedline - at the antenna. I
keep a chart of what antenna has which value resistor.
Two reasons for the chart.. if the resistor changes value, I can find it
quickly. IF I drop a coax into a couple others, I can quickly determine which
antenna is connected with which feeder. The resistors are all under 2 watt.
Since I generally run qrp, the summertime "missing" resistor, leads me to
believe "there went another strike".. and the discolored ones, make me believe
that even at 2 watts, the wind static has power.
Have a great day,

Subject: Re: Topband: choke/bleeder resistor on RXvertical?
Question about the use of Ohmite bleeder resistors: What are the considerations
relative to power rating in this application? Would a 2w OX or OY ceramic
resistor survive extended use of full legal amateur power limit on such modes
as RTTY, FT8, JT65A, SSTV, and various other high duty cycle digital modes, and
AM voice, etc?
Best regards,
Gary, K7EK
