Isopole antenna design. Is an ideal choice for base stations. All Isopole antennas yield the maximum gain attainable for their respective lengths and a maximum signal on the horizon. To get your copy or information about ordering an AEA ISOPOLEm write or call Advanced Electronic Applica tions Inc PO.
All Isopole antennas yield the maxium gain attainable for their respective lengths and a maximum signal on the horizon. Outstanding mechanical design makes the IsoPole the only logical choice for a VHF base station especially for Packet operation. A standard 50 Ohm SO-239 connector is recessed within the base sleeve fully weather protected.
A monopole antenna is a class of radio antenna consisting of a straight rod-shaped conductor often mounted perpendicularly over some type of conductive surface called a ground plane. The highly advanced technology in the design of the decoupling of the transmission line as regards the antenna produces a predictable radiation pattern enhancing the performance so the energy is radiated at a low angle and completely. Tunes Performs Without Radials or Antenna Tuners.
The Isopole antenna used multiple sleeve sections to decouple the feed line and it probably was one of the best. Because most so239 connectors have a square flange and a hole in each corner its customary to use 4 radials. Some of Kathreins aka Scala antennas are by design fairly immune as are some of the original Kreco designs.
AEA Isopole 144 Jr2 m. Exceptional decoupling from the feed line results in simple tuning and a significant reduction. AEA Isopole 144 Sr2 m.
Outstanding mechanical design makes the IsoPole the only logical choice for a VHF base station antenna. All IsoPole antennas yield the maximum gain attainable for their respective lengths and a zero degree angle of radiation. Easy Quick and Simple Installation.
I observed that effect for myself with the aidof a simplepickup loop and pilot lamp sensor as described in AEAs booklet Facts About Proper. Standard 1-14 Inch IV mast. If you find one of these at a hamfest for 20 buy it.
The driving signal from the transmitter is applied or for receiving antennas the output signal to the receiver is taken between the lower end of the monopole and the ground plane. Next cut a section of 1 pipe long enough to mount the antenna where you want and push it into the bottom of the 34 X 1 tee. This latest design is easy to assemble and to tuneresulting in a very good package for the price.
Make sure all your pipe is together tight and at this point if you want to use pipe glue do it. Exceptional decoupling results in. Durable Construction Can be Used in Extreme Weather Conditions.
Exceptional decoupling from the feed line results in simple tuning and a significant. With a radical advanced design for vertical omni directional VHF antennas the SPECTRAL IsoPole has obtained a strong reputation through the years offering exceptional characteristics compared with any other type of antennas as. On 6232019 529 PM skipp025 via GroupsIo wrote.
The lower cone is a decoupling sleeve for the antenna mast. Offers a rugged design which will withstand the harshest weather. Patented IsoPole conical sleeve decouplers offer many design advantages.
The installation of the SPECTRAL IsoPole is very simple it requires only a metallic tube not supplied with the antenna for a reason of length of 32mm 1-14in and 3 meter 10 feet for VHF 135-160 models model of higher frequencies accept shorter masts and the UHF models are supplied with their own masts and it is only necessary to. Available at most local hardware stores. Box 2160 Lynnwood Washington 98036 Call 206775-7373 Introductory Price Isopole 144- 4995 Isopole 220- 44 95 I I For the first time ham opera.
Each IsoPoIe is factory tuned and only requires adjustment of the element lengths the field. The AEA Isopole 144 Jr. More than 12 months.
Stabilizing Cone Discs 1800 Shipping. The Spectral Isopole is very similar to the AES Isopole. Now you can rebuild your Old Isopole antenna.
With the IsoPole design and superi-ady compelled another r t. IsoPole Antennas Oulstanding mechanical and electronic design makes the Isopole the on- ly logical choice for a VHF base station especially for Packet operation. If you make a side by side comparison to a Cushcraft Ringo Ranger II a Comet GP-15 or a Workman UVS-200 the Isopole seems like a poor performer.
The gain over a dipole is now a few db at some really low angles so it can be better than a dipole. Antennas by AEA The IsoPole has built a strong reputation for quality in design and superior performance. Handles Up to 1000 Watts PEP.
Ail Isopole antennas yieldl the maximum gain attainable for their respective lengths and a maximum signal on the horizon. The highest cone is to form the lower half of a half wave vertical element. The site of the Legenday Queen of the VHF and UHF omnidirectional Antennas Manufactured by Spectral Engineering.
If space does not allow extra height or decoupling radials then this isopole is. The IsoPole antennas were desiãled to mount on a low-cost. Decoupling Cones are NOT for sale.
Replacement Parts For Isopole Antennas. Outstanding mechanical design makes the IsoPole the only logical choice for a VHF base station especially for Packet operation. Performs about like any other single element 58 wave antenna Time Owned.
Cut one last 34 piece of pipe about a foot or so long and hold on to it for use later. Here is the most basic of antennas. If changes in mast length or feed line length or grounding affect the antenna pattern or SWR it is an antenna design problem.
If you are looking for reliabilitythis is the antenna that combine good gain and bandwidth with compact size. Antennaslowprofile and adaptability forportable installations make it well worth considering ifyoure looking fora new2meter antenna.
