[KYHAM] Advice About HF

[Bill L. Fuqua]

The G5RV will not tune up on all bands. It wa a designed during the days of tube final amplifiers which could handle high SWR.   It  is a source of a lot of mythology today. You would be better off with a true multiband antenna with traps. The traps also function as inductors on lower bands that allows the antenna to be shorter in length. The resonant length of the parallel feed line is often a problem with the G5RV if you don't have space to run it. You can't just roll it up to get it out of the way. 

If you are not limited in space a mult-wire dipole is the best. That is an antenna with a dipole for each band terminating to the same feed line. Only the dipole that is resonant to the operating frequency takes energy from your transmitter. These can be condstructed from readily available items or you can buy one already made. 

One last thought. The G5RV was developed when there were only 5 useful HF ham bands. 160 was not available to most hams then and we did not have the WARC bands.

Subject: [KYHAM] Advice About HF 

Hello, 

I have just recently aquired a Kenwood TS-2000 and I
am learning the morse code ( slowly but surely ). I am
trying to get suggestions on what would be a good HF
antenna to use. Some people have told me a G5RV will
work since I have an internal antenna tuner inside
that radio. Then some people have told me to not get
one because their junk and doesn't work for nothing.
Also if a G5RV is recommended how does it need to
hang. If you can kinda give me direction and advice
right now all I'm doing is listening but I know as
soon as I get the General Ticket I will want to be on
there so I figured I'd go ahead and get it going. 

Thank You
