I recently noticed I was missing a few pages from my site, one included a great article I wrote on antenna stacking and baying. So I am going to try and reproduce it here.<\/p>\n\n\n\n
Ah, my fellow radio enthusiasts, gather around the virtual campfire as we delve into the electrifying world of antennas. Picture this: a moonlit night, a cosy shack, and a cup of metaphorical cocoa. Let\u2019s break down the antenna stacking and baying dance steps, shall we? \ud83c\udf19\ud83c\udf99\ufe0f<\/p>\n\n\n\n

Stacking vs. Baying: The Cosmic Dilemma<\/strong>:\n
\n
Imagine antennas as celestial dancers\u2014one twirling above the other (stacking) and the other waltzing side by side (baying).<\/li>\n\n\n\n
Stacking: Antennas in a vertical embrace, like star-crossed lovers reaching for the sky.<\/li>\n\n\n\n
Baying: Antennas holding hands horizontally, a cosmic conga line across the rooftop.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
The Gain-Beamwidth Tango<\/strong>:\n
\n
When we stack or bay antennas, we\u2019re after gain\u2014the celestial spotlight that makes our signals shine brighter.<\/li>\n\n\n\n
But beware! The gain comes at a cost: beamwidth. Like adding too many sequins to a dress\u2014it narrows our focus.<\/li>\n\n\n\n
Imagine stacking directors: more gain, but a beamwidth so tight, it could thread a needle in a hurricane!<\/li>\n<\/ul>\n<\/li>\n\n\n\n
Real Estate Jitters<\/strong>:\n
\n
If you\u2019ve got acres like a Texas rancher, stack away! But in a built-up area, an 8×8 array is like fitting a giraffe into a Mini Cooper.<\/li>\n\n\n\n
In the UK, we\u2019re more practical\u201444 arrays on VHF and above are our jam. Urban chic, if you will.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
The Boxkite Intrigue<\/strong>:\n
\n
Box kites, those mysterious rebels, defy the norm. Their feeding secrets? A tale for another page\u2014stay tuned!<\/li>\n\n\n\n
Spoiler alert: It involves secret handshakes and moonlit rendezvous.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
The dB Dilemma<\/strong>:\n
\n
Stacking promises 3 dB of gain (or so they say). But in the real world, it\u2019s more like 2.5 to 2.7 dB.<\/li>\n\n\n\n
Connectors, coax lengths\u2014they\u2019re like dance partners stepping on each other\u2019s toes. Gain wobbles.<\/li>\n\n\n\n
And those pesky sidelobes? They crashed our antenna party, uninvited.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
The S Point GAIN Mystery<\/strong>:\n
\n
Ah, the million-dollar question: What\u2019s the benefit of an S-point gain? Is it a cosmic currency?<\/li>\n\n\n\n
Let\u2019s just say it\u2019s like finding an extra marshmallow in your cocoa\u2014a sweet surprise.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n
So, my radio comrades, whether you stack, bay, or invent new antenna moves, remember: the dance is in the details. May your signals reach the stars! \ud83c\udf1f\ud83c\udfb6<\/p>\n\n\n\n
