2M HO LOOP STACK KIT
Mount both antennas with no phasing cables installed. Make
sure the feed connectors are facing each other and the larg-
er feed blocks are on the opposite side on each anten-
na. (2M and 222 only). Creating a 180°phase shift.
Connect your feedline to the top antenna and tune to reso-
nance (see tuning instructions).
Connect your feedline to the bottom antenna and tune to
resonance at the same frequency as the top antenna.
Connect the phasing lines and adjust both antennas in
equal dimensions to resonate the system (as needed).
Route your main feedline as shown, seal and water proof
your system appropriately.
It is much easier to tune HO loops using an antenna analyz-
er, since your initial tuning may be beyond the transmit
range of your radio. HO loops are sensitive to their sur-
roundings, so it is best to tune the antenna(s) in their final
position, whenever possible.
