4 Softrock v6.2 receivers in parallel to facilitate phased antenna, K1LT
I've designed a circuit board for 4 Softrock v6.2 receivers in parallel to facilitate phased antenna studies
7 mhz vertical monopole
7 mhz vertical monopole high efficiency half wave vertical radiator fisical lenght 8
A 90 foot Irrigation Tubing Vertical
For the past couple of years I have been experimenting with making vertical antennas out of aluminum irrigation tubing.The most frequently asked question I get about this is: how do you raise the thing?
