Fred: You would need a resistor which would handle the power AND the voltage it would see; for legal limit transmit power, many otherwise-suitable resistors have insufficient voltage rating. Phil AD5X uses one or more 3M¦¸ high-voltage resistors:
You could also use a choke, Phil shows the construction of a legal-limit HF bias tee, the choke in it should also do the job:
For less than legal limit power much less robust (and cheaper) components could be used. Of course chokes are frequency-sensitive unlike resistors.
Bleeders are only required for antennas which do not have a DC return between center and outer conductors; many dipoles or verticals with baluns or transformers, folded dipoles, Yagis with folded dipole feeds or hairpin match, etc. already have a DC return inherent in their designs; a quick measurement with an ohmmeter will tell. If it shows a low resistance a bleeder is unnecessary.
I also use gas-discharge tube arrestors on ALL of my antenna feedlines and rotor control lines, with the gas tubes sized for the power levels to be used; in my station, receive only, rotor(56V), 100W (150V), or 500W (1000V). My arrestors, which have replaceable/swappable gas tubes, are mounted directly to one of my 4 station ground rods using DX engineering mounting clamps: Replacement gas tubes are available inexpensively from distributors like Digi-Key. I mark the arrestor with the installed gas tube's voltage for easy reference.
Here is a QEX article with more information:
My station has already withstood a nearby lightning strike, unlike my fiber internet modem/router and everything on my wired network, including some of the wires!
The arrestors are for lightning protection only, they will NOT bleed down to a low-enough voltage to protect a network analyzer input!
Even with bleeders installed it is good practice to short out any cable before attaching it to an instrument.
