[TowerTalk] Temporary 160 meter antenna question

[K4SAV]

For your 1 day option of running an 80 meter dipole on 160, here is a 
piece of data for you.  Assuming an antenna height of 50 ft, if you are 
feeding the dipole with 100 ft of RG8X, loss in the coax on 160 meters 
will be approximately 18 dB.  For 100 watts in, you get 1.6 watts radiated.

Feeding it as a tee without a good ground will work better, but you will 
light up all your equipment.  I wouldn't run phone, you may need your 
lips for something later.
