Free delivery and returns on eligible orders. 5-meter loop antenna and coupled to an amplifier circuit which matches the low impedance of the loop to the 50 impedance of most receivers. The design is composed of two broadband discone -type antennas (75–7075 MHz), a single-pole double- throw (SPDT) switch to select the desired antenna, several filters to remove undesired out-of-band and overloading FM signals, a low-noise preamplifier to enhance … is connected to a laptop via Ethernet and controlled by a tailor-made. We also stock all the leading brands of amateur radio accessories and have one. It is extended for use with Radio Sets AN/GRC-27, AN/GRC-29, and AN/TRC-32 which communicate with UHF command radio sets in aircraft and such ground UHF stations in the terminal area. 95 WiNRADiO AX-71C Discone ANT01 $89. Chalk up another victory for my cheap Radio Shack discone! During the 8 year course of ownership of this antenna, it has survived tropical storms and hurricanes in Florida, blizzards and 'noreasters in Rhode Island and most recently my little discone acheived another victory; surviving a direct hit from Hurricane Ike. > Don't forget that a discone is a vertikal groundplane ant so you lose a lot of signal at higher elevation (as mutch as -100dB direct overhead). Palomar Loop Antenna Manual Included is a copy of the original instruction manual with dimensions and I have a very nice Palomar Engineers Loop Amplifier with 3 plug in antennas: I hooked one up a Palomar Loop Antenna (that works great with my CC Radio) but it doesn’t work on my Superadio. discone or double discone. 4-8-8 Nakameguro, Meguro-Ku, Tokyo 153-8644, Japan VERTEX STANDARD US Headquarters 10900 Walker Street, Cypress, CA 90630, U. MOR Mobile Roof Mount Antenna 30-50, 130-174, 450-512 & 800-950 MHz. At the time of these attic adventures, my attic antennas included: 2 m and 440 J-Pole; 2 m and 440 slim jim; 9:1 unun fed 32 foot longwire, a Diamond Discone antenna and a noise dipole cut for 20 m to use with my MFJ 1026 noise canceling filter. Omnidirectional, vertically polarized and with gain similar to. The AR5000A+3 is a good receiver, but you may find that in the Greater. Radio Shack Discone 20-043. Buy MOONRAKER MRP-2000 MKII PRE-AMPLIFIER- BNC 25-2000MHZ - (Qty:1) at Amazon UK. So the PGA-103+ will work as a loop amplifier, but the mismatch loss means that the noise figure and gain flatness is not as good as it really needs to be for this application. Sorry if a similar question is buried amongst the older posts, they take some searching when a word is commonly used I am considering purchasing a pre-amplifier with in built filtering akin to the M100 by Moonraker, I have watched a few you tube videos and they seem to perform reasonably well but a few videos is not enough to swing my decision so I thought I would ask the forum members what. Model BDA-230/A is similar to Model BDA-210/A but the frequency range of operation is from 2 to 300 MHz. May 11, 2006 at 11:39pm. Tram Antenna found in: CB Base Antenna, No Ground Plane, For All Applications, Scanner 25MHz-1,300MHz VHF/UHF Super Discone Base Antenna Plus CB Transmit Bands, Oil-Filled Coil CB Antenna, BIGCAT-9 CB Antenna, 46" VHF Marine. I get great reception on 11 meter (CB) and VHF (marine) bands. Understanding Shortwave Antennas: Page 14 Add-On Gadgets.

For 500MHz to 200MHz the double discone would probably just about beat the Dressler, from 2000MHz to 50MHz and below the double discone would be better.
