content: Hard to say, could really be anything.I would imagine by it's size that it is either a dipole, or it is some kind of end-launch planar structure (yagi, vivaldi, etc) in an array?

content: Look like some Ghz Antenna.Maybe for Mobile Internet?In Austria "Mobile" Internet is cheaper than DSL so many People use such Antenna for a better Signal.

content: Seems some patch antenna for wifi or GSM, or follow the airplains in flight radar, but definitely in the Ghz range

content: Most likely a PCB antenna for 4/5G reception, seeing it mounted up there up high, likely in an area with either poor reception or with coverage from a carrier you do not want to ever deal with again, but the competition signal is barely usable at ground level, so the need for a directional antenna to get you a decent coverage signal.

content: Go near the pole, and try to make a clear pictures of the labels, from underneath. One of them should most probably have an FCC-ID printed on it. Search online for the FCC-ID to find the producer, some specs of the equipment, etc.https://fccid.io/

content: Looks like an RTV DVB-T/FM antenna, but the connector seems to be an N type which would be quite unusual for a TV/radio antenna. So I tend to agree with SeanB.

content: It’s a secret 5g antenna probably being used to program the local bats.Not really. We wouldn’t give away our secrets like that.But I am interested to see what the answer is.

content: Quote from: Lord of nothing on April 07, 2020, 03:02:27 pmI didn't talked that this is exactly this device.I just show an example of device for satellite communication with similar shapeI think it also may be some kind of flat panel satellite antenna. Something like that:https://www.nationaldefensemagazine.org/articles/2017/6/28/new-flat-panel-satellite-antennas-hitting-the-market

content: Directive as it is placed at side of an aluminum tube.By feeding point, it is not an log-periodic antenna, seems to be a short Yagi.From holes at side of enclosure does it seems to be missing a part of VHF antenna.[ Specified attachment is not available ]

content: If it was a satellite antenna it would be very unlikely to be pointed to the horizon.If it was a patch (or array of patches), the main lobe would be pointing directly up in the sky, so unlikely.I’d guess it’s a directional antenna, probably a yagi, and possibly multi band, fabricated on a PCB substrate, which is why it’s in a radome.Difficult to gauge the size, it could just be a UHF terrestrial TV antenna. Whatever it is, it’s for a terrestrial service.

content: If it is simply a passive element .. no amplification .. I don't think an FCC ID would be required. My guess is a housed log-period antenna using horizontal polarization. But, facing up .. something for a geo-sat.

content: No it is not a log periodic antenna. Can easily be judged be design. Cable feed in middle of enclosure and squarish enclosure. A log periodic antenna covering some bandwidth is always much more narrow at end of antenna and then normally resulting in similar shape also for the enclosure, which it not is.It is limited space for a cable to leave at middle of enclosure of an log periodic antenna. Compare how cable is leaving enclosure at photo.Cable leaves antenna at antenna structure end for an log-periodic antenna and by then normally also end of enclosure. Can be seen in many 3G-4G log-periodic antennas.From size, look at pole size, and possible fitting inside cover is possible half wave-length around UHF => an ordinary TV antenna.These short antennas are usually useless without active amplifier and its elements of weak design why it needs that big plastic cover in opposite to TV antennas of less weak design.Look at mounting bracket, it is obviously an integrated part of antenna enclosure design. It is prepared to be pole mounted either horizontal or vertical. That is for sure not a satellite related polar mount. Its function is much more likely to be able to select vertical or horizontal receiving polarization which mainly can be of use for improved TV reception.It really screams "I am a cheapo TV antenna". Guess it is sold as a camper antenna. Can be good enough antenna in many cases if local signal coverage is good.

content: Found it.It is a Philips TV antenna just as I wrote. It is stated to be digital so it is a very remarkable antenna:https://www.philips.ca/c-p/SDV8625T_27/digital-tv-antenna
