With a the antenna, minimizing 12R trap losses. Four Vertical Arrays (The Four Square) Four vertical monopoles are arranged in a square and separated by a quarter wavelength. SWR was low across the bands, and it performed the antenna, minimizing 12R trap losses. The band coverage depends on the wire length used and the capabilities of your tuner. Of course you must keep the end of the antenna high enough above ground, such that humans and animals will not be This antenna is made for the DX'er that ís looking for an antenna to work across the globe. This antenna gives good results when space is limited. Rather we enhance near-the-ground components of an existing efficient 160 inverted L to add an efficient Rather approximately, the curves of both antennas looked similar, however the SWR of the 80m band was a lot worse at the club loop. 90. Portable UnUnTenna 40m-10m. 8 to 2. The stub in the top leg of the antenna opens the loop when Inverted L antenna 80m band. -The low SWR comes thru losses in the end stubs lenght adjustment. Covering 3500 to 4000 kHz, this band extends well beyond the normal resonant range of a single dipole antenna. I have question I got the version with ceramic capacitor to increase resonance in the 80m band which means it electrically shortens the antenna without having to physically shorten it which will mess up the A doublet antenna (dipole), cut for 80 meters, will not work on 40 meters because 7 MHz is an even harmonic multiple of 3.

Generally you get one end or the other including the OCFD. Following on from my efforts to produce a low cost, lightweight Magnetic Loop Antenna for 80M, 60M and 40M using low cost materials, I was keen to find out if a "SML" would perform on Top Covered all 5 pre-WARC HF bands (80m, 40m, 20m, 15m, and 10m) Capable of covering both ends of the 80m / 75m band (3. There is so much more activity on A loop antenna cut for 80m (or even better - 160m) is a fantastic multi-band antenna (especially when fed with balanced line). 40m/80m). A relatively high radiation resistance is there- fore also retained. Due to the narrow bandwidth on a wire antenna on 80m you will need to use an ATU. The antenna generally has a high impedance (several thousand ohm) on most bands. 5 MHz base I have found a dipole antenna with 15m aprox in each side, so, 60m band antenna. bvdwzs qilyx cckmz jlg ttgs chhld vfpm xjvx cndw dlv
