A 6 element Low Noise, High Gain Directional Loop array (LFA-Q)
G0KSC LFA-Q possesses all of the design traits InnovAntennas have
become well-known for. Direct 50 Ohm impedance (and hence no matching
loss or pattern distortion). Minimal side lobes, High levels of Front
to Back ratio (F/B) and Front to Rear ratio (F/R), and wide, flat
bandwidth. However, the LFA-Q stands out for two more major benefits.
High levels of forward gain and its' extremely rugged design which make
it ideal for installation where harsh weather conditions are
you want the absolute best performance from minimal boom length and
require performance that is available in any weather conditions or
simply want something a little different, then the LFA-Q could be the
one for you!

Customer comment on the LFA-Q:
''Very nice...assembled and installed over the last two days - even though it arrived over night!
extremely well - It replaced a MET 144 8T (remember them) that was
about 20 years old - the gamma match had become unstable - suspect the
trombone dielectric has aged/decayed.
This antenna has great FB like the MET but I think gain is very comparable and bandwidth far, far superior.
Thanks for the great service
This antenna is made with tapered elements 1/2inch(12.7mm)
centres and 3/8 inch (9.525mm) outer sections. The antenna has fully
insulated elements which will ensure continuous, high performance for
many years to come. Boom to mast brackets are included with all antennas
which will support 2 inch (50mm) masts. The LFA-Q has a twin-boom system. Each section is38.1mm squarewith
1.6mm wall thickness. The booms are joined each end to one another by a
second piece of the same material used for the boom. A UV protected
Boom Guy system is also provided with stainless steel turnbuckles for
LFA-Q is also provided with 2 boom to mast brackets, one on each boom
and both brackets comprise of 4 U bolts (2 square for the boom, 2 round
for the supporting mast) which have been formed from marine grade
antennas are constructed with the best quality materials in order that
the best mechanical construction can be achieved, not the cheapest and
most profitable! Even a digital caliper is used (with an accuracy of
.01mm) to measure the elements during production to ensure they are
within 0.2mm of what they should be, ensuring they work as well as our
software model predicts.
Much development time has gone into our antennas, not just on basic
electromagnetic design, we are able to model the effect of insulators,
booms and other objects to ensure the make up of our antennas have least
effect on performance and pattern degradation. More information can be
