[ForSale-Swap] FS MFJ1798 80 METER THRU 2 METER ANTENNA

[Jimmy's mail]

The following is taken from mfj's website about the antenna.


I am asking $150.00 firm plus shipping total cost
after shipping $175.00
This antenna sells for $290.00 plus shipping so get it while I have got
it....

P.S. it is in the Box ready to ship........




Operate 10 bands -- 75/80, 40, 30, 20, 17, 15, 12, 10, 6 and 2 Meters with
this MFJ-1798 vertical antenna and get full size performance with no ground
or radials!
Full size performance gives high efficiency for more power radiated.
Results? Stronger signals and more Q-5 QSOs.
Full size performance also gives you exceptionally wide bandwidths so you
can use more of you hard earned frequencies.
Full size performance is achieved using separate full size radiators for
2-20 Meters and highly efficient end loading for 30, 40, 75/80 Meters.
Get very low radiation angle for exciting DX, automatic bandswitching,
omni-directional coverage, low SWR. Handles 1500 Watts PEP SSB.
MFJ's unique Elevated Top Feed elevates the feedpoint all the ay to the top
of the antenna. It puts the maximum radiation point high up in the clear
where it does the most good -- your signal gets out even if you're ground
mounted.
It's easy to tune because adjusting one band has minimum effect on the
resonant frequencies of other bands.
Self-supporting and just 20 feet tall, the MFJ-1798 mounts easily from
ground level to tower top -- small lots, backyards, apartments, condos,
roofs, tower mounts.
Separate full size quarter wave radiators are used on 20, 17, 15, 12, 10 and
2 meters. On 6 Meters, the 17 Meter radiator becomes a 3/4 wave radiator.
The active radiator works as a stub to decouple everything beyond it. In
phase antenna current flows in all parallel radiators.
This forms a very large equivalent radiator and gives you incredible
bandwidths.
Radiator stubs provide automatic bandswitching -- absolutely no loss due to
loading coils or traps.
On 30,40, 75/80 Meters, end loading -- the most efficient form of loading -- 
gives you highly efficient performance, excellent bandwidth, low angle
radiation and automatic bandswitching.
MFJ's unique Frequency Adaptive L-Network provides automatic impedance
matching for lowest SWR on these low bands.
Tuning to your favorite part of these bands is simple and is done at the
bottom of the antenna.
you don't need a ground or radials because an effective counterpoise that's
12 feet across gives you excellent ground isolation.
You can mount it from ground level to roof top and get awesome performance.
The feedline is decoupled and isolated from the antenna with MFJ's exclusive
AirCore high power current balun. It's wound with Teflon coax and can't
saturate, no matter how high you power.
Incredibly strong solid fiberglass rod and large diameter 6061 T-6 aircraft
strength aluminum tubing is in the main structure.
Efficient high-Q coils are wound on tough low loss fiberglass forms using
highly weather resistant Teflon covered wires.
