This
antenna is made from 2 inch pvc pipe,
and the bottom mounting system is interchangeable. The pole mount
is shown. The antenna has a SO239 connector at the base to connect the
supplied delay line and choke. On 40 meters the delay line is 21 feet
long and is not part of the radiating section. The radiating part of the
antenna is 80% of its length from the top down. SWR is 1.2:1 and the
bandwidth is ~150 khz to the 1.5 vswr points.
This antenna can (in some installations) cover the whole 40 meter band with a swr of
less than 2:1. The antenna is weather proof and can tolerate winds of
70 miles an hr. The pole mount is designed to slide over a antenna mast
which is less than 1.25 inches in diameter, (most are 1 inch) with a
stop bolt preventing the mount from sliding into the antenna. The stop
bolt can be removed and you can drill a hole into the mast and put the
bolt thru the mast and mounting pipe for a more secure mount. We have
had no problems with just sliding the antenna onto the mast and
forgetting it. Total length with the mounting pole is ~6 ft. The pole mount itself is
~4 ft long and can be cut shorter if needed. You can paint the antenna any color you
desire as long as there is no metal in the paint. You can place the
antenna on the floor in an apartment, or window, or on a table. The only
requirement is that you not place any metal objects within a few feet
and do not set it on a metal table.
Specs: MM40-1
Height: approx. 2.5 ft
Weight: approx. 8 lbs.
Gain: 3 dbi / 2 dbd, based on testing. Read
design page or testimonials.
SWR at resonance: 1.2:1~ *
1.5 SWR Bandwidth: aprox. 150 khz.
Note: I recommend a antenna tuner for maximum bandwidth and use of the
band. It does not effect performance.
NOTE:
Center frequency is 7.200 Mhz, if you want a
different center tuned frequency change it when you
order. Enter it in the box to the left of this page.
Power handling: 600 watts CW, 1 Kw SSB.
Mounting: Pole up to 1.25 in. / or Floor/base mount. Specify which one
when ordering. Pole mnt is standard
1 year limited warrantee.
Note: Floor mount is not for setting on the actual ground. It is for
apartments or tables that are aprox. 4 feet or more off of the actual
ground. Setting the antenna on the ground will prevent it from radiating
efficiently. It will also weaken the receiving properties when setting
directly on the ground.* Resonance is affected slightly by
positioning of the delay line. This does not affect
performance. However it will shift the swr point a
little. With a tuner you can easily cover the whole
band and Mars / Cap frequencies or I can adjust it
for you when you order. |
