Shunt-Feeding a Short Tower on 80 and 160m
Run a wire all the way to the top of the tower sections, then measure the impedance at the bottom, then design a matching network to match the resulting impedance

Antenna 80 meter Links →
Isotron antenne Voor de 80m band
For the 80 m band the coil is wound with black 1.5 mm² installation wire of approximately 10 m length. The antenna resonates at 3,630 MHz with this
Inverted-L for 80m & 160m
On 80m very good performances with very acceptable noise level. Made several comparisons with EWE antenna's and magnetic loops - the very weak stations were always readable
Short verticale per i 80 metri
Si tratta di un tubo di plastica del tipo per impianti idraulici, lungo poco meno di due metri 1850 mm
80-75 Meter 4-Square Array
The SWR from 3.5 to 3.9 is below 1.5:1, the F/R of the array is 20dB average and with some signals even better
Antenna for 80 meters in garden 46ft
A 46 ft multi band antenna for small gardens that works well on 80 metersMain bands 50 ohm are 80m / 40m / 30m / 17m / 15m / 12m, Other bands 20m / 10m
