InnovAntennas DB-664 Compact 6 and 4 Meter Dual Band Yagi has a total of 6 elements; three elements are for 50 MHz and three are for 70 MHz, available on many radios made for the European market. For those in North America where the 70 MHz band allocation doesn’t exist, several new transceivers, including the Yaesu FTDX10 and the Icom IC-7300, offer receive coverage of the 4 meter band. Even though transmit is disabled in NA, the 70 MHz band may be monitored for signals arriving from Europe, for those interested in VHF propagation.

InnovAntennas DB-664 6 Element Dual Band Yagi for 50 and 70 MHz

The InnovAntennas DB-664 Dual Band Yagi stands apart from the crowd due to the methods used for its design. It has no traps or coils, no phasing arrangements and has no need for 'compromise' spacing between elements. This antenna has a set of correctly spaced elements for each band, but requires only one feed point. The DB-664 is an excellent antenna with great SWR bandwidth and performance in one package.

The InnovAntennas DB-664 antenna has 6 meter element with 1/2 in. (12.7mm) center and 3/8 inch (9.525mm) outer elements and the 4 meter elements are one piece 1/2 inch. The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. The boom to mast brackets and clamps included with all antennas will support 2 inch (50mm) masts. The rigid, heavy-duty boom is 1.25 inch square 16-guage aluminum and marine-grade stainless steel hardware is used. Our antennas are constructed with the best quality materials to achieve the best mechanical construction, not the cheapest or most profitable. A digital caliper is used to measure the elements during production to ensure they are within 0.2mm of what they should be. This ensures that each antenna works as well as our software model predicts.

Note: Much development time has gone into our antennas, not just on basic electromagnetic design. We are able to model the effect of insulators, booms and other objects to ensure the components of our antennas have the least amount of effect on performance and pattern degradation.
