    Adding 5 ohms reactance to the 160 meter 4-square elements is just like 
tuning down frequency about 20kHz from a verticals resonance. They have about 5 
ohms reactance of their own then. Adding the arrestors to each element is like 
moving the resonant frequency up about 20kHz. Fortunately 4-squares generally 
are very forgiving of their elements resonance. If your 4-square had good 
bandwidth before it likely will not change much except to shift its design 
frequency up a little. 
    My 2 cents or .005 gallons.   Lee K7TJR OR
