[TowerTalk] another stupid guywire question

[K5MLC (Mike)]

Does anyone have any idea if 3/16 7x19 galvanized "aircraft cable" with a burst strength of 4200lbs would be OK to use instead of EHS for guying a 51' rohn 25 with a cushcraft A3S/743 40 meter adon antenna sitting atop ?  Also, is there a "rule of thumb for dumbies" as how to not have the metal guywire resonance on HF - (ie how far apart do you place those glass eggs? Do all the guywires need them, or just the closer ones to the antenna?) Thanks in advance de K5MLC
