5 cze 2021 · Here is a simple antenna calculator for two popular forms of ham radio HF wire antennas: the horizontal dipole and the inverted "V". (Updated June 5, 2021) The Antenna Calculator. for. Half-Wave Dipoles. Enter your desired frequency (MHz) of operation (i.e. 3.55).
23 paź 2011 · Here is a spreadsheet I designed in Microsoft Excel for calculating the first cut and the final cut (after testing) of a 1/2 wave dipole, whether center-fed, classic off-center-fed, Windom, or New Carolina Windom.
very ham needs at least one antenna, and most hams have built one. This chapter, by Chuck Hutchinson, K8CH, covers theory and construction of antennas for most radio amateurs.
Dipole Antenna Calculator. The measurements below are for building a simple Dipole Antenna. The Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth. The antenna is designed to be fed with 50 or 75 Ohm Coax Cable of most any length with a Balun.
114 - Six-Band Wire-Stub Trap Antenna for 40m-10m 115 - Multiband Half-Wave Delta-Loop Antenna 116 - Hybrid Vee for 20m, 17m 117 - Six-Shooter Array Antenna, Gain=7.5dB 118 - Multiband Ground-Plane Antenna for 10m, 15m, 20m 119 - Wire Superbeam Antenna for 10m, 15m, 20m 120 - Two Elements Delta-Loop Antenna 121 - Sterba Curtain Antenna
Fortunately there is a starting formula for these types of antennas. For center fed, wire dipole antennas, the formula is 468/freq(mhz). Enter the formula for the antenna:
Enter the formula for the antenna calculation (normally 234/f): divided by Freq. MHZ. The vertical length is feet. The 4 radials are each feet. Halfwave Verticals. The halfwave vertical antenna consists of a vertical radiator which is fed from the bottom of the antenna.
