. The advantages of these antennas are directional good front-to-back and smaller than a Yagi. Admittedly you could space the Yagi Antenna elements longer or the same as the quad for better front to back ratio but then the gain drops to below 11 dbi. 2 ELEMENT QUAD 1011 METER N1UUE says take your pick 17 METER 3 ELEMENT YAGI Direct feed - N5DRG HORIZONTAL MINI V BEAMS Using MFJ HF Verticals 2 ELEMENT DIRECT FEED YAGI Design it for any band MORE BELOW.

I am use to using a external tuner for these bands but my Yeasu FT450D had no problems with its internal tuner to match any of the eight bands. A Loop antenna is formed by a single or multiple turn of wire forming a loop.

At that point it is bend towards the house about 30 cm above. Chaowei Digital TV Antenna-DVB66 Portable Indoor Outdoor TV Antenna with Magnetic Base165ft Long CableOmnidirectional Receiving-Support 4K 1080P TV. 20995 Inc VAT at 20 Add To Cart View Details Wishlist.

A YagiUda antenna or simply Yagi antenna is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array. At the same time it must be clear of all guy wires or metal.

The Directional Forward Gain and Front to Back Ratio FB Ratio features are hallmarks of the Yagi and the reasons for its high. I actually gave the Yagi some optimization because on the same 65 boom length of the cubical quad the results are just terrible for the Yagi like 2 db down versus the quad.
