experimental type aerial maybe similar to an nrg vertical

I would share plans for interesting aerial I made tuned to about 89 mhz, it a long pole in mine 118 cms, with a shorter wire 62 cms, the middle of the wire taped closed to the bottom, with it flopping either side like a bow tie. I use 75 ohm coax rg6 and 2 turns at the bottom just under 10 cms.

Its good aerial, dispite the lenght of the pole been less than a half wave lenght, I change it for a higher frequency by moving the blue wire further up where its attached with velcro, you can also run it along side the main pole afew cms away. It is a wider band aerial than most, can be, but still needs to tuned to the frequency to get the best reception, it may be related to the nrg half wave.

the 1 i made afew months was longer 148 cms using 69 cms wire, had swr of 1.5 over the whole band, it took ages to do, this 1 is useble all the way from 88 to 96 mhz!
