Hello,
The maco Y-quad isnt a cubical quad.
Its two yagi's one vertical and one horizontal and a wire well...to make it look interersting. That refelector wire gained hugh fame due to the avanti moonraker antennas...But..these antennas will still have issues with the metal mast.
It will work... but not as good as a single quad.
Which is logical as you think of it....
Within a fraction of an inch you carfully set your element lengths and distances out of the box acoording the manual
...and then "poef" you just set a hugh metal mast in between them and then expect it Not to have any influence..
So all antennas who have the elements "in line" with the mast ... are to be avoided.
The best way to go is either stack 2 side by side or go for a cubical quad like the ones from Cubex, or perhaps from lightning.
That is... if you want vertical and directional.
But if it were me... i would stick with horizontal and put a metal antenna on top of it.,
PS
A cubical quad antenna is an antenna where all the elements are in a square shape and are roughly a fullwave lenght in circumference.
PS2
You might get the advise to go for a delta loop and change the angle to 45 degrees... that will work ...(you can also do this to a normal yagi (rotate it 45 degrees)) it is a better solution then putting a yagi completly vertical or to use that so-called Y-Quad..but then again...it is with reduced performance... its works... but not to its capabilities.
Hope it is of use,
Kind regards, Henry
