- OK. I have a NAD 4225 Stereo tuner. I also have a external 28? element
- UHF antenna aimed at the local TV (and FM radio) source 7km (~4miles) away.
- The antenna has no "line of sight" problems with the translator, however,
- I do have a problem with ghosting, althought not bad, should be better
- given my setup. This, I am told, is caused my the proximity of the flat metal
- roof, which the antenna sits about 2m ( 6feet) above.
-
- My problem with FM reception is as follows. I have tried BOTH connectiing to
- the external UHF antenna, via a 75ohm coaxial cable, and using an internal
- 300ohn dipole antenna. With both I get annoying high frequency interference.
- The only work-around at present is to press the BLEND botton on my tuner
- , which eliminates the interference, but sadly, a lot of the hi-end as well.
- As I enjoy recording simulcasts of classical presentation on the public
- TV channel I would like to know how I could improve my FM reception.
-
- Do I but an external FM-audio antenna or, as a freind suggested, raise the
- height of the UHF antenna to about 5-6m (15-18feet) from the flat metal roof.
- My feeling is the latter may improve my TV(video) signal, but is the antenna
- too selective for FM(audio) use?
-
- Thanks is advance.
