Wire Antennas for the Beginner - ARRL - Home

install an antenna where it can contact a public utility wire. You may have a pair of 70-foot trees perfectly positioned to sup- port a wire beam aimed at your favorite DX area. But if a power line runs between the trees, forget it. If you have plenty of room for a real antenna "farm," then a separate antenna and feed line for each band is the winding with foam filled hot tapered pultruded antenna tankWhat makes a good antenna for a boat?The strength of the transmitted signal available to a distant receiver depends largely on the performance of the antenna. Since the boat is free to maneuver, the antenna must radiate equally in all directions.See all results for this questionWhat happens to the antenna on a ship?However, as the vessel rolls and pitches, the antenna will no longer be vertical. The signal radiated from the more directional 6 or 9 db antenna may then be directed upward into the sky or downward into the surrounding sea, rather than in the direction of the horizon.See all results for this question

Weatherproofing Kit for Connectors and Antennas

Wrap the connection with a layer of 3/4 (19-mm) plastic tape, starting at 1" (25 mm) from the con- nector or plastic strain relief of a SureFlexjumper. Overlap the tape to half-width and extend the wrapping to the flange of the antenna connector. Avoid making creases or wrinkles. Smooth the tape VHF Radio Antennas | BoatUSDepending on antenna length and design, this type of antenna can have a power gain of 6 or even 9 db. The law against free lunch also applies to antennas. The greater the gain of the antenna the more directional it becomes. Everything is fine as long as a 6 or 9 db antenna is vertical and stable.Stop antenna wind noise easily and permanently Allan's winding with foam filled hot tapered pultruded antenna tankUPDATE 2018: I had some concerns about long term use after the mods to stop antenna wind noise but after using the modded antenna for two years, it worked perfectly. The antenna has stayed in place, has not bent too much, and of course, is silent. I have not had to do anything as far as repairs or adjustments and the antenna still works perfectly.

Making a DIY emergency VHF aerial | YBW Forum

Jan 14, 2010 · Channel 16, which is likely if you are using an emergency antenna, is 156.800Mhz Therefore the 1/4 wavelength vertical antenna for Ch 16 should be 1ft. 5 - 15/16in. or 0.455 M If you were considering the whole range of Marine VHF - then that is 156.000 to 161.975 ( including M2 and the AIS) M2 is 161.425 requiring 1ft. 5 - 13/32in. or 0.442 MInsulated grp frp fiberglass tube winding machine for winding with foam filled hot tapered pultruded antenna tankTank Winding Machine Fiberglass Tube With Foam Filled Hot Jizz Grp Frp Tapered Pultruded Antenna Fiber US $300.00-$1000 / Cubic Meter 1 Cubic Meter (Min.
