Flower pot antenna calculator. Half wave flower pot antenna 2m or 2m 70cm dual band image 1 the basic vhf 2m design this is the basic 2m half wave antenna using grey 25mm conduit to build a dual bander with 70cm capability continue the steps from page 4. The one of the simplest antennas to make for hf is the dipole antenna. Does any one know how to calculate the length of the cable and various other relatedd dimentions.
Here is a link to his webpage with instructions for making several of his designs. Flower pot antenna. Nylon line 500mm al foil longer conduit will give more room below the coil to attach to the.
Po zestrojeniu pracuje w paśmie 2m i 70cm. To work out the length of a dipole use the calculation 468 divided by the frequency. To construct the antenna first select a suitable length of grey 25mm conduit as a minimum 1m but if you make it longer you will have more room below the coil to attach to your antenna support.
I ve found a. It had been about 10 years since i used 2 metres actively. The 5 8λ radiator uses a 0 2λ shorted co ax phasing stub to resonate the 5 8λ element.
Take a look at the first drawing. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole. Flower pot antenna calculations i have rg 59 cable with 75 ohms of impedence.
I figured it was time to get back into the band. It is best to cut the antenna for the center of the band in question. The results are conveniently displayed in inches centimeters feet and meters.
