Take A Sneak Peak At The Movies Coming Out This Week (8/12) Miley Cyrus kicks off first Big Concert for Small Business; Will Smith gearing up to get Fast & Loose I have not noticed any ill effect from them in my operations perhaps because the nulls are broad and also the deepest part of the nulls lay along a 90 – 270 degree azimuth, from my QTH there is not much DX from those headings. ... D eciding to put up a loop antenna can be more of a logistical problem than an engineering problem in the initial phases of your project planning. The following is an article which I wrote and was published in the February 2013 edition of the Central Coast ARC … Alpha Delta was correct that the antenna is mechanically stout. The right angle delta generates slight more gain than it’s equilateral cousin and the shorter height makes it an easier install for those amateur operators with limited height supports. The loops are symmetr… Often that match is a quarter wave matching transformer made from 75 ohm coax that is inserted inline between the coax feed line from station and the antenna feed point but due to my vision impairment I was not able to build one. https://amateurradionewsinformation.com (Amateur Radio News & Information). Matching such an impedance and driving it with a feed line without excessive line loss presents another problem. However, you may find that your mono band delta loop may tune up on it's second harmonic at a higher frequency eg. When I first built it, I fed it from the top (apex about 50 feet or so). Within this physical description there are two distinct antenna types: The large self-resonant loop antenna has a circumference close to one wavelength of the operating frequency and so is resonant at that frequency. After a week I decided to feed it from the corner. The transmitter generates a radio signal. "Delta loop" implies a vertical deployment, and vertically deployed loops are usually useful only on their fundamental band.
