Hello,

This antenna is only suitable for vertical installation, which may be a problem as Werk_AG wrote yesterday in another thread
(TX on the roof and below it RX). On the other hand, it can be quite effective in field use. The basic problem: the datasheet
does not show the profit/loss of the entire assembly. And I'm afraid that the lineup will have a loss rather than a gain because
of the length of the cable. But without the manufacturer's data or measurements, it's just "divination from the ball". Positioning
upside down seems completely nonsensical - the antenna radiates minimally in its vertical axis. And the wire-simulated ground
should always be a ground not a ceiling.

But: I never used this antenna, so this information may not be guaranteed, it results from my experience. The antenna is very often
used to connect radio stations (HAM), eg in the 27 MHz, 134-174 MHz, 430-490 MHz band, ... But the transmission power used starts
at tens of W and ends at kW ...



Our recommendation for small antennas with a gain of 2 dBi with their correct polarization still applies (all antennas point in the same
direction, perpendicular to the plane interspersed with all transmitters and receivers).

Thank you for your input, learned a bit more!
