Triband Receiving Loop for 160/80/40m

Triband Receiving Loop for 160/80/40m

The loop is the unshielded type constructed from RG-11. The benefit of the shielded type loop construction seems to be in loop balance and that is said to improve null depth

Loop per la banda degli 80m
Con l'uso di questo loop per la banda degli 80m, si intende cercare di migliorare l'ascolto di questa difficile banda radioamatoriale

Low Bands aplifiers LNA 1.8-3.8MHz, IZ3ETC
As an amplifier I used the famous 2N5109 for its excellent features of high OIP3, low noise figure in push -pull configuration.in input to the preamp I put a bandpass filter that passes the signals of the two low bands 160 meters and 80 meters , but which cuts the AM broadcast frequencies to about 600KHz, the frequencies of 40 meters and above. Possibly the filter can be removed and the preamplifier can make the whole band from 200 KHz to 30MHz

Low Band Receiving Loops and the Evolution of the Trapped Inverted L
Is a trapped inverted L. I made the trap from RG400 coax and PVC pipe. The trap is tuned to the low end of the 80 meter band

Low-noise receiving antenna for 80 and 160 meters, K6STI
The Square is simple to build, install andtune. Here I'll tell you what's required to make 21-foot Squares for 80 and 160 meters, or a single Square that works on 80 or 160 meters at the flick of a switch

My 40/30/20/17/15/12/10 meter phased vertical antenna system, W8DIZ
The Square is simple to build, install andtune. Figure 1 shows the Square as viewed from above. Here I'll tell you what's required to make 21-foot Squares for 80 and 160 meters, or a single Square that works on 80 or 160 meters at the flick of a switch
