Cantenna or Can't I?

Cantennas can handle far more than 200 watts.

All light bulbs with filaments have the same problem.  They change impedance as they heat up.  Boatanchors with the older final networks could handle a lot more variation of loads than modern transistor rigs.  The older rigs, I am most familiar with Heath and Johnson, often listed 60 to 100 watt light bulbs as proper loads and showed pictures of hooking your rig to a porcelain socket setting on your bench.  
One other thing, a lot of halogen bulbs are low voltage and low wattage.  I wouldn't want to hook up to a bulb rated at 12V and 5 to 10 watts unless it was truly a QRP rig!  Hi, Hi.

Hi all:

Would like to know how many watts ...and how long...I can put into a 
Cantenna.

I have a vintage linear I'd like to get up to working...called the Shoebox 
II...schematic in July 1967...4 x 6HF5's...200 watts p.e.p. each or 150 watts 
c.w.

Also...anybody ever use a halogen bulb for a dummy load?
