DBJ-1 Dual Band VHF/UHF 2 meter/70cm ham base antenna

Description

DBJ-1 dual band VHF/UHF base antenna
Why buy from imitators?  Buy it from the original
inventor (Dr. Ed Fong WB6IQN – Univ. of California at Santa Cruz- Silicon Valley
Campus) with 100% lifetime warranty and help out his graduate students at the
same time.
If
anything ever goes wrong, just return it and it will be either repaired, a new
one sent to you or a full refund (buyer’s choice).  This is the same
antenna that was featured in Feb. 2003 QST.
This
antenna is complete with exception of the 5 feet of ¾ inch Class 200 PVC
pipe needed for the antenna.  A photo is attach and shows what is in the
package.
Individual shipping of the 5 ft
antenna is $14 so we rather you go to Lowe’s (stock # 23990) or Menard (SKU
#6899684) and buy the PVC pipe for about $1.  If you cannot find the PVC
pipe, I can send it, but you will need to pay the postage.  Please email
me if you need me to send the PVC pipe.  Assembling is
straightforward.
No tools, no glue.
Just slip the antenna into the PVC pipe, hand
tightened, and you are ready to go.
