Hello
I have bought an antenna in secondhand an antenna MFJ-1782. I have some problems to obtain good results for the SWR .My antenna is in vertical polarization. I use this antenna with a battery.. I have only a good SWR in the ten meter band ( 1.1) but when the frequency degreases , the SWR increases very rapidly . On the 20 meter band , the SWR is near 3-3.5 - The coax is H100. I tried with differents lenghs of coax . ( 5 , 10, 15 meters) and the result is the same. I don't know what I must do. I write you ( in bad English and excuse me) to say if you have a solution to my problem.. I thank you in advance 73 |
