I was reading the information on the Par end fedz antanna and found it interesting.  I used to love to work 10 through 40 meeters.  so 20 meeters would be interesting to me.  one question I thought of was how much of a problem would a person have wit television interference on this  band?  I was wondering now that most people use cable and satellite for television reseption has this minumized the problems people has had with TVI in the past?  although I have never used it I heard one problem people who used CB had was CB transmited on 27 mHZ and the second harmonic of 27 is 54 the old VHF television band.  I was also curious to know does any one know what frequency satellites use to transmit signals back to televisions?
Before I lived in a moble home when I was on 10 through 40 meters.  since apartments are so much closer together will this increase the problems I would incounter with TVI?
Thank you for the information in advance.
