The computer shows that the antenna (mounted 1 foot above ground) has a gain of about 1.5 dbd higher than a dipole's gain (also mounted 1 foot above ground.) the second reason you may want to use the 5/8 wave vertical is to obtain a lower angle of radiation. a half wave antenna's radiation peak angle is 20 degrees.

The 5/8 wave antenna. at vhf, both the 1/4 wavelength monopole and the 5/8 wavelength monopole antennas are widely used. the vhf 5/8 wavelength (144 mhz) vertical monopole has long held the reputation of providing about a 3 db gain advantage over the 1/4 wavelength vertical monopole. # 2: 49.1 8.4 small mine: 42.5" 19.5" 2.5" where l (lambda) = wavelength i've made at least four of these things; basically, one 10 foot length of half inch copper and four matching elbows should come out just right (allowing about a half inch each direction for each joint, this takes 2x19 2x41=120 inches of pipe). but when i couldn't get the. Many am broadcast transmitting antennas are tall (at $\nu \sim 1$ mhz, $\lambda \sim 300$ m and a $\lambda/4$ vertical antenna is about 75 m high) towers acting as quarter wave verticals. the conducting ground plane is a mirror that creates the lower half of the dipole as the mirror image of the upper half.

Vertical polarization 5 – 8 elements fm log antennas with 6 7.5dbd gain, fm log antennas 5 and 8 elements, wide band, entirely made of aluminum and stainless steel screws, they are light and completely demountable. all the metal parts are electrically grounded, they have a diagram of radiation without secondary lobes. Each pôle length is lambda / 4 143/2f = length of each radiator element in meter. pvc pipe is about lambda / 4 long from the reflector. use 50 ohm coax câble if the antenna is well done, this. Increase range of simple low power fm transmitter by yagi antenna: introductionfor good efficacy and directivity for reception on radio spectrum, we need a good yagi uda antenna. this antenna was invented in the early 20th century by two japanese engineers named uda and yagi. the yagi antenna is a narrow band ant. The 5/8 wavelength vertical also requires a ground radial system to realize its full potential. the radial system needn't be an extensive affair buried in the ground. i used six elevated 5/8 wavelength radials for my antenna. thanks to the ladder line, the 5/8 wavelength vertical also is usable on 20 and 15 meters. Elti fm vertical dipoles are completely broadband from 87,5 108 mhz with constant gain over whole fm frequency band. fma 2 10/50 antennas are lightweight and cost effective solutions, available with n, din 7/16 or eia 7/8” connectors, made completely of aluminium.

Da 1005 directional fm antennas. the eri, da 1005 series fm antenna is pole or lambda™ mounted and designed to radiate power in a highly defined directionalized pattern. this dual polarized antenna is ideal for fm stations operating under a fcc construction permit which requires a directional antenna pursuant to docket mm87 121. the da 1005. A ground plane antenna is a λ/4 vertical element that works against a ground plane, a large metallic surface, the earth, or, in some cases, an array of conductors called radials. Antenna's are resonant at 1/4, 1/2, 5/8, full wave, multiples of full wave and several other multiples. you could create a simple dipole for your fm radio by taking a piece of two conductor speaker wire, compute your size by taking the middle of the fm band, 98mhz would be close. 300/98 = 3.06 meters. At first the antenna was modeled by copper wire. then the antenna was made on the base of bicycle wheel spokes. . pdf file, 170 kb (antentop 01 2015, pp: 71 72) download pdf file! html version. contents for antentop 01 2015. vertical antenna 5/8 lambda for 70 cm band.

A six bay full wave spaced antenna has a gain of roughly 3.3, which is similar to the 3.1 gain from a 10 bay half wave assuming circular polarization on both. the half power beamwidth of the main lobe in the vertical plane for the full wave is around 4.2 degrees compared to roughly 5.2 degrees for the latter style antenna. Requiring a new 2 metre band antenna for local fm simplex and repeater communication and after evaluated a couple of the main contenders for the project i settled on the 5λ/8 wave ground plane to be designed for approximately 146.5mhz. for an example of a practical development of a 5/8 wave vertical antenna for the 4mtr band see:. Most of them tend to stick to vertical antennas with a 1/4 or 1/2 wave sizing. just a happy few build a 5/8 wave vertical antenna. this is remarkable, since the 5/8 has the lowest angle of radiation and has about 1db more gain (compared to 1/4 and 1/2 verticals). so the 5/8 should be the favourite choice for dx’ing. Fm antennas are provided to you by progressive concepts serving all your radio broadcasting equipment needs. we carry a comprehensive collection of fm antennas, including broadband and dipole antennas. contact us today for additional information about our antennas. You would think a 5/8 wave antenna would be better because of its 3dbd gain, but the 1/4 wave has really surprised me at times. i have both and sometimes the 1/4 will pick up things the 5/8 will not and vice/versa. the best thing to do is to get a nmo mount and buy a 1/4 wave and 5/8 wave and try them both and find out for yourself.
