[TowerTalk] t type antenna

[w5jmw at towerfarm.net]

Hello all.I have a t antenna.50ft vertical and roughly 300 ft ntip to 
tip horizontal.I get a nice drop and resonance at abt 3.8 mhz.Is this 
weird resonant point normal??I would think it would be lower.I have 
another at abt 2.2 but almost a 3-1 swr..Normal ? I have used an 
inverted l before and resonant was abt right with a 1/4 wave 
length..thanks..john
