ELEMENTS and slide each phasing line into one pair 3/8” clamp blocks. Allow the ends of the phasing lines to
TEMPORARILY stick out 4” past the ends of the clamp blocks. Now pull the phasing lines back, guiding them
into the clamp block set on the other driven element. Now re-tighten the four 1/4-20 locknuts.  Set the insulator
about midway between the two elements and secure it with large nylon tie inserted through the bottom hole and
around the boom. TIP: ( For maximum life of the cable tie, cover the tie with 2 to 3 wraps of Scotch 33 or
equivalent black electricians tape).
11. BALUN INSTALLATION
Refer to the figures 6 and 7 on DUAL DRIVEN AND T-MATCH ASSEMBLY for this procedure.
Loosen the 2-1/2” U-bolt on the L-bracket and insert the 4:1 HF Balun with the connector facing towards the front
of the antenna. MOUNT WITH THE DRAIN HOLE DOWN. Position the Balun so that the U-bolt hits the edge of
the front cap. Now tighten the U-bolt just enough to hold firmly in place. BE CAREFUL! Over tightening might
crack the case of the Balun. Remove the wire balun leads shipped with the balun and install the “L” shaped
straps on each of the balun mounting posts. (shorter side).

12.‘T’-MATCH INSTALLATION
Refer to figure 6 on DUAL DRIVEN AND T-MATCH ASSEMBLY for this procedure.
Locate the two 1/2 x 23-1/2” ‘T’-Feed tubes and 3/8 x 10” fiberglass insulator. Install the 3/8” fiberglass insulator
into one of the 1/2” ‘T’-feed tubes. Align the holes and temporarily secure with a 8-32 x 1” screw. Now feed the
undrilled ends of both ‘T’-feed tubes into the two ‘T’-match shorting bars. Slide one of them back so you can
install the other end of the 3/8” fiberglass rod into the other 1/2” tube. Align the holes and secure with another 8-
32 x 1” screw. With all of the hardware loose, rotate the entire ‘T’-Match assembly up so that the two 8-32
screws fit right into the two Balun straps. Secure the two 8-32 screws with two 8-32 locknuts. Now set the two
shorting bars to the dimensions shown on the DIMENSION SHEET and tighten all the hardware.
13. Now it is time to install the completed tip sections. Refer to the main overview of the antenna called the
“KT34M2 DIMENSIONS SHEET”. Paying close attention to the DIMENSION SHEET, and the ORIENTATION of
the CAPACITORS, insert the individual element halves for the REFLECTOR into the swaged ends of the 1 x 72”
tubes. Secure them with 8-32 x 1-1/4” screws and locknuts and tighten securely.

14. Now move on to the REAR DRIVEN ELEMENT TIPS AND

BE CAREFUL!

This element is not installed in

the same orientation as the REFLECTOR. Add the hardware and tighten as before.

15. Continue by adding the FRONT DRIVEN ELEMENT TIPS and then the DIRECTOR TIPS. Secure them with
8-32 x 1-1/4” screws and locknuts as before and tighten all hardware.

16. BOOM TO MAST PLATE INSTALLATION
Locate the boom to mast plate, 3” U-bolts & saddles, and 2” U-bolts & saddles. Install the four 2” U-bolts on one
side of the boom to mast plate. Center the plate at the location shown on the DIMENSION SHEET, and install it
using the 3” U-bolts, saddles, 3/8” nuts, and lockwashers. If possible, attach the feedline to the balun and route
it back to near the boom to mast plate and secure. Seal the connector with black tape, coax seal or equivalent.
A 3” U-bolt pattern exists should you need to mount the antenna to a 3” mast.

This completes the ASSEMBLY. REMEMBER to support the feedline at the antenna boom and on the mast.
Leave an adequate feedline loop for rotation around the tower.

REMEMBER YOU CANNOT STACK A TRIBAND BEAM WITH ANOTHER ANTENNA WORKING ON THE
SAME BAND AS THE TRIBANDER. Serious interaction will result and loss of performance of both antennas
maybe noted. Two KT34M2 tribanders can be stacked together but the spacing must be at least 32 feet apart.
When stacking this antenna with other H.F. models like 17 and 12 meters, maintain at least 8’ separation; more if
practical. Mount horizontally polarized 2M VHF and UHF antennas at least 40” above or below this antenna to
minimize interaction. We have noticed that large 2 wavelength ( 40 foot) long 6M Yagis even stacked at 10 feet
above will interact and can cause some loss of front to back on the tribander.
