[TowerTalk] 75 ohm feedline

[Bill Fisher, W4AN]

I dont understand the need for these boxes if you are feeding monoband
yagis.  The ARRL Antenna Handbook and ON4UN's book both describe how to use
asynchronous transformers out of coax.  I use them for all my antennas.  No
failures yet.   N4RJ used these boxes on his 10M stack.  A little water...
and BZZZZT... QRT.
