Topband: Two Wire Beverage antennas

[donovanf at starpower.net]

Hi Carl, 


I've never used an MFJ-1025/1026 so I can't comment based on direct 
experience. Perhaps someone else can comment. 


The DX Engineering NCC-1 is exceptionally well engineered for ease of 
use, its the ideal tool for creating deep steerable nulls with two wire 
Beverages or just about any other combination of two vertically polarized 
antennas including a pair of close spaced 8 to 25 foot tall verticals on a 
very small lot.

Frank, does that work with the MFJ-1025/1026?
