Greetings,

I have for sale a new-in-crate, unused Force12 MAG620/340N antenna. 
This is a MONSTER 6ele on 20M and 3ele on 40M on the same 47ft 
boom. It has 18.5sqft of windload and requires a tower such as 
Rohn-45/55, and a healthy rotor such as an Orion-2800 or a prop 
pitch unit. The June 2011 cost for this antenna is quoted as $5,367 
plus $400 shipping from TX to KY.

I ordered (full-payment in advance) this from Force12 five years 
ago in the spring and it took almost 24mo to get it to my door. 
Between the production efforts, material supply issues and other 
problems, and the continuous delays, I opted for other antennas. I 
ended up using a 4ele20M 36ft boom and a 4-square on 40M.

I have this unassembled antenna kit (crate is 150" x 25" x 25" and 
400lbs) in my garage. The 47ft boom starts out 5" dia, tapers to 
4", then 3" and finally tapers to 2-1/2". The mast plate (actually 
a cradle) is made from 18" x 18" x 1/2" aluminum, and all the 
elements are very heavy duty (N=100mph). The up-the-tower weight is 
stated to be 250lbs, but may be slightly more.

My preference is to sell it pickup-locally. However, If you wish to 
use a freight carrier, I am good with a prepaid shipment. I am 
located in Nicholasville, KY outside of Lexington.

$3,999 (save $1,768 w/pickup) or best offer...........

"Magnum 620 and the 3 element 340N: Several enterprising customers 
added the "N"series elements to their existing Magnum 620/340 
antenna, with excellent results. We took the hint and expanded the 
design to accommodate the larger "N"series 40 meter elements. The 
boom has been increased in diameter and extended out to 47', plus a 
drop-in cradle mount. "
