4 element 28MHz LFA Yagi (4.5m)
- Brand: InnovAntennas
- Product Code: 4 element 28MHz LFA Yagi (4.5m)
- Availability: Not in stock
A 4 element 28.0-28.6MHz LFA Yagi
The G0KSC LFA Yagi represents a major step forward in the development of the Yagi Antenna, it provides a low-noise front-end for your radio so you hear more weak signals while at the same time maximising all round performance. Hard to beat with a direct 50 Ohm feed-point and no matching losses and suppression of unwanted noise!!
NOTE: With all our HF antennas we can custom design your element taper and element size requirements in order to cater for all weather and installation requirements

This antenna is made 5/8 inch (15.88mm) centre elements and 1/2 inch (12.7mm) outer elements with the end sections 3/8 inch (9.525mm). The antenna has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with all antennas which will support 2 inch (50mm) masts. Boom is 1.5 inch square 16SWG aluminum.

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable! Even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production to ensure they are within 0.2mm of what they should be, this ensures they work 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 make up of our antennas have least effect on performance and pattern degradation. More information can be found here
