Therefore, using the APR to extract high-frequency (HF) antenna patterns at. This occurs because the radial system raises the "Q" of the antenna system. If you think this is bad, imagine what happens with an end-fed antenna (even a 1/2 wave antenna) and NO radials! In that case all of the antenna current flows over the feed line shield! Many antenna designs actually use the feed line and mast radiation that others dismiss as "insignificant" to increase antenna gain. The antenna requires a manual or automatic antenna tuner either in your shack or remotely located at the antenna feed point. Commercially made portable antennas do work if you can afford them. Warranty 12 month. but hey, isn't that what antenna building is all about. The output from the AA30 showed the following values: First measurement, no radials, steelpipe mounting. Resources listed under Vertical Antennas category belongs to Antennas main collection, and get reviewed and rated by amateur radio operators. I am wondering if 16 66' and 16 33' radials will be just as efficient for the higher bands as would having fewer radials separately cut for each band of interest. { * simplifie d : no reactance } In FREE SPACE , 100w fed to the antenna radiates 100w even though the SWR is about 1. 95 * Buy It *After Coupons & Promotions. 50 radials is not too many. 5 - 57 MHz (80 Meter - 6 Meter) • Frequency Range RX: 2 - 90 MHz • Antenna Type: Omni Directional • Antenna Whip: Aluminium, No Radials • Antenna Length: 6 meter • Max Power: 400 Watt • Connector: UHF-Female (SO-239) • Packing: Box. >> Could you recommend me a HF vertical multiband antenna >> (80,40,20,10 or more bands) which doesn't require >> radials? > > Is there a commercial HF vertical available in > Spain that doesn't require radials?

But, first, to better appreciate the characteristics of this portable antenna, I believe it is important to first review the. 6-80 Meter BASIC-FMJ portable HF antenna. (A sloping wire has essentially the same vertical and horizontal. But most say 1/4 wave radials are an important minimum no matter what the height. Most internal rig auto tuners do not have adequate range to match the high impedances presented by S9v43 at various HF frequencies. There is no "good" HF vertical that doesn't have something to balance the vertical part of the antenna. Excellent performances,ideal for QRP stations and for local difficult environment. By John Portune W6NBC. It will probably take several trips from your shack out to the antenna and back shortening or lengthening the elements.
