well today i finished putting my dipole up
it's a center fed 25ft hot side 40ft approx rfgnd side. at the base of a mast (5ft) i have a sgc237 tuner feeding 5ft of 450ladder (to the dipole) with lmr400 (150ft run) one for hf one for 2/440 and one 8conductor 18ga control ccable for tuner unfortunately i am about 4-5ft away from the building master antenna--had no choice here I did put a pro tvi filter just before the master tv ant amp by ice Seems using about 20watt i can tx from 160-6m w/o any problem w/ 2 exceptions i noticed on a quick test **1) i have 2 tvs a 'good' sony and a old toshiba , on 20m cheep set will loose a little color when i tx it kinda makes bright red for ex. into a dull red (all colors). using a set side radio shack tv filter(back of tv) didn't help seems to barley effect 4-11 but 2 and 13 are most effected on my cheep set this practically had no effect on the 'good'sony note: i have good grounds and lightning protectors inline and on my rig, (both rig side) .. i also have a w2du balun near the sgc237 and i also tried a drake tvi filter by my rig guess it's the 54mhz cut off kind (didn't help) ***2 on ten meters I whipe out ch2 herring bone fuzz both sets again filters set side didn't help I also tried a drake hf tvi filter on my rig no effect it's a bit strange i seem ok on 6m thought for certain i'd blow there but we all know 10m can also cauz a bit of tvi question: anyone have any ideas how i might be able to reduce/elim the prob on 20 as it seems small,, and perhaps someone smarter than i might also have a few tips for clearing up 10m i guess having most bands but two isn't bad, thanks all m |
