Tonna F9FT - Mounting of Antenna to Mast; Stacking

For proper mounting coax connector, see connector mounting instructions,
for the UG 21B/U. On the main feed-line (RG 213/U or better) a type N
female connector (UG 23B/U) must be used. If bigger coax is used, use a
special connector with same nose as UG 23/B/U.
MOUNTING OF ANTENNA TO MAST :
CAUTION
No piece of mast or tubing must run through the element plane. Performance
may be reduced !
It is recommended that the antenna be mounted on top of the mast, or if not
possible, along the mast, using an offset arm, about 1,5 wavelength long
minimum. Mast up to 54 mm (1" 1/8) diameter are accepted by the attaching
set (see medalion n° 6).
It is also recommended that the antenna be placed in direction of dominant
winds when not in use.
STACKING
To simplify the stacking set-up, the short length of coax is part of the
phasing harness itself.
In order to put the antennas in phase, make sure the plastic injection studs,
on the driven element stand-off, are all facing to the same side
A special quarter-wave power splitter is available in two version :
4 jnputs 50 Ohms, one output 50 Ohms : part n° 29423
Output available in 75 Ohms upon request.
A complete stacking frame kit, for three wavelength spacing is also available,
part n° 20016 for horizontal polarization, ant 20017 for vertical polarization.
The power splitter is designed for stacking four antennas. A combination of
five of these splitters allows stacking of 16 antennas.
NOTES
1) Do not use spacing shorter than 3 wavelengths (700 mm, 27" )
2) The complete set : 4 antennas, part n° 20423
1 power splitter, part n° 29423
1 stacking frame, part n° 20016
Is directly available, with part n° 20696
