Disadvantage: Moving It
If you employ a little TV-top antenna, you need to attempt multiple pole placements before finding the most precise reception position. Each pole generally rotates and extends, creating trouble to manoeuvre one so the opposite incessantly whereas seeking most reception. For out of doors antennas, there is the adscititious trouble of getting to mount up the roof or sub the weather whereas adjusting your antenna. Some out of doors dipole ANtennas have forward administrators that stretch out from the most antenna at an angle, creating somewhat more sophisticated adjustment.
Disadvantage: Size
Although the indoor dipole antennas square measure typically little, the out-of-door versions are often giant and troublesome to manage. They typically need quite one person to put in because the poles could be tall and unwieldy. The dimensions make these out of doors versions troublesome to move, move and install once necessary.
One disadvantage of a horizontally mounted dipole is its reasonably high elevation angle (the signal goes "up" at a sharp angle). This isn't notably sensible for DX (very long-distance work). You'll be able to overcome this by mounting it vertically - then you get a pleasant shallow angle. However, that gets very tall for a few bands, and conjointly, it rolls your signal onto its facet in theory. Therefore it won't take a couple furthermore with a horizontally mounted antenna.
Also, it's not spatial relation (if it's horizontally mounted). You don't get a lot of a symptom off the ends - it essentially goes dead set the facet. This may even be overcome by mounting vertically.
It's very reasonably a shame that the majority of dipoles out there square measure mounted horizontally. If the common follow were to travel vertical, then long-distance communication in any direction would be started.
I appear to possess some recollection that when the signal has bounced off of a layer within the part, then the polarization becomes mixed, so that side of vertical vs horizontal could also be a dead letter. I'm very undecided of that in the slightest degree tho' - I could be memory one thing else and obtaining my wires crossed.
