Directional antennas<\/a> are also called plate antennas. They radiate in a certain angle range in the horizontal pattern, which is what we usually call directivity. In the vertical pattern, they are beams with a certain width. Like omni-directional antennas, the smaller the lobe width, the greater the gain.Directional antennas are generally used in communication systems with long communication distances, small coverage areas,large target density, and high frequency utilization.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Q1: What devices and scenarios is this antenna for?<\/strong><\/dt>
Perfect for handheld spectrum analyzers, portable SDRs, two\u2011way radio repeaters, tactical radios, and emergency comms kits. Typical uses: multi\u2011band field coverage testing, public safety\/temporary communication networks, long\u2011range point\u2011to\u2011point links in mountainous areas, and pre\u2011compliance EMC tests.<\/dd>
Q2: Are the eight bands continuous or do I need to manually switch?<\/strong><\/dt>
The antenna has independent resonators for each band \u2013 no internal switch. Just connect it to your device, and it will work for any frequency inside the listed segments. No manual tuning required.<\/dd>
Q3: What does “gain 4-6\u00b11dBi” actually mean?<\/strong><\/dt>
Typical gain varies by frequency: around 4dBi on lower bands (e.g., 350-400MHz) and up to 6dBi on higher bands (e.g., 930-1020MHz), with \u00b11dBi variation. The main lobe is narrow with good side\u2011lobe suppression \u2013 great for directional \u201creach\u2011out\u201d links.<\/dd>
Q4: As a handheld panel antenna, do I need to aim it?<\/strong><\/dt>
Yes. Directional antennas have a maximum radiation direction (the front face of the panel). Point the front toward your target. The horizontal beamwidth is about 60~80\u00b0, so small misalignments are fine, but large deviations will noticeably reduce gain.<\/dd>
Q5: Can it handle simultaneous TX\/RX at 50W?<\/strong><\/dt>
50W refers to the maximum continuous wave (CW) or FM peak power the antenna port can withstand. It supports full\u2011 or half\u2011duplex operation as long as you stay below the power limit. Always use with a radio whose output power \u226450W and keep VSWR within \u22642.0.<\/dd> <\/dl>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
