[600MRG] XSV only RX until further notice....

[Edward R Cole]

This begs a question as I thought RF voltage was peak at the end of 
an antenna and RF current peak at the feed.  But what should one 
expect at the antenna end of a base loading coil?  I am using one 
inch diameter by ten inch long pvc tubing for my base insulator and 
also hang the coil with the same tubing from a wooden enclosure.  The 
top end insulators are 12-inch ceramic-glass.

The antenna went up last night with the eme array so I could try 
receiving signals.  We are in a storm with winds up to 30mph so 
static noise might be high.
