They have a slight amount of gain IAOI they have a good ground plane. The additional gain of a well designed 5/8WL vertical is, IMO, only important for HF CW DX and QRP digital work. On another topic, Would it be bad to use RG6 for the antenna and radio? "Bad" is relative. RG6 is 75 ohms. When I was in high school, RG6 & RG11 were very popular. If a center-fed dipole has a feedpoint impedance of 73 ohms, then 75 ohm coax results in a very low SWR on the feedline. The mismatch, is this case, is at the source and is not anything to worry about. Of course, your SWR meter, calibrated for 50 ohms, will not display the correct SWR on the 75 ohm coax. In the '50's, if our transmitter's pi-net output would "load", our system was working just fine. Most of us didn't even own an SWR meter back then. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- If my swr meter wont work with 75 ohm cable, should I use rg58 thsn if I cant find rg8? |
