MFJ 1899T Telescoping Antenna

Jumper connections are numbered 1 through 6 with
#1 closest the BNC connector and #6 at the top

80 meters (no jumper connected) - whip approx. 48"
40 meters (#1 connctected to #2) - whip 47"
30 meters (#1 connctected to #2) - whip 15"
20 meters (#1 connctected to #2) - whip 39"
17 meters (#1 connctected to #3) - whip 47"
15 meters (#1 connctected to #4) - whip 21"
12 meters (#1 connctected to #4[5?]) - whip 48"
10 meters (#1 connctected to #5) - whip 39"
 6 meters (#1 connctected to #6) - whip 33"
4? meters (#1 connctected to #6) - whip 19"

Length of telescopic sections are for lowest freq.
in band and with ground plane wire connected to
radio.  Best length for ground plane (radial) wire
is less than 1/4 wave 180 divided by freq(in MHz)=
length in feet.  Telescopic sections can be adjusted
for best SWR.

With #1 connected to #6 it will also make a
reasonable 5/8 wave on 2 meters and Airband.
Telescopic length on 2 meters -- approx. 45"
Telescopic length on Airband --- approx. 50"
