INTRODUCTION
Thank you for choosing InnovAntennas.
Many dual or multiband Yagis suffer compromising effects as a result of negative interaction between
elements in use and others on the same boom. However, 6m and 10m are two bands where the impact is
small. If sufficient time and attention is taken during the optimisation process, excellent performance in
terms of gain, Front to Back (F/B) and bandwidth too.
Additionally, our 6m/10m range has been optimised for use with a single feedline. This reduces the
requirement for additional coax and connections on the station amplifier or transceiver and ensures
transfer of common mode currents along a secondary feedline back into the shack does NOT occur.
Additionally, both bands can be watched at once on the same radio upon individual VFOs. They single feed
line is therefore ideal for SDR and contest grade radios.
Our Yagis are designed and optimised by computer mechanically as well as electromagnetically and the
same taper scheduling per band (elements) is used throughout our range. Thanks for this superior
mechanical optimisation goes to K7NV (sk) and his exceptional ‘Yagi Stress’ calculator software.
We hope you enjoy the use of your InnovAntennas dual bander for many years to come. It has been
designed to provide many years of trouble-free service.

BOOM ASSEMBLY
Frontally match the boom sections with the same letters (AA, BB, CC, …).
The boom parts with the same cross-sectional sizes are joined by one or multiple boom insert(s) as shown

ELEMENT ASSEMBLY
The 28MHz and 50MHz elements are mounted to the boom differently from one another. The 28MHz
elements are held in place with plate which support 2 insulator holders for each element (one either side of
the boom) whilst the 50MHz element are held in place by a single insulator bolted directly to the boom.
For the 28MHz mounting plates, there is a single hole in the boom to be married with the central hole in
each element plate. The counter-sunk bolt secures the plate followed by a secondary (smaller) plate on the
reverse side of the boom. The boom is sandwiched between the top plates by means of 4 x M6 bolts.
For the 50MHz elements, just 2 x M6 bolts secure the single element holder in place per boom position.
These bolts pass through the insulator (two halves) that have the 50MHz element centre between them
and are bolted into a pair of threaded boom inserts pre-set in the boom itself.
10 m / 28 MHz ELEMENTS (Reflector REF + Director(s) D1, D2, …)
The element plates (EA01025…) are fixed to their according boom position with a screw DIN7991 M6 x 30
mm through the plate’s central borehole. These element plates will hold the 28 MHz elements
The central parts of the elements are secured on the element plates by the green isolator plastic blocks
EAHYP020 and the according socket head screws, spring washers and self-locking nuts.
The central parts of the elements are easily recognizable due to their slits on both ends, while the extensions only
have slits on one end, the element tips do not have any slits at all.

10 m / 28 MHz ELEMENTS (driven element DE with feed point)
The active element has central screw terminals and a center insulator. It is secured fourfold to the
element holder as shown below. Otherwise, the mounting material is the same as shown on the
previous page.
6 m / 50 MHz ELEMENTS
These elements consist of a central part (diameter 16 mm) and one extension (diameter 13 mm) on each
side. Use the green plastic blocks (EHAYP016) and screws DIN 912m M6 x 40, to mount the elements to
the boom.
