Hi All

Looking for a little help I'm going to build a top loaded vertical for 160m

I have about 70-75ft vertical and was thinking about using 4 wires off the top 
to make up the difference,

My garden is not in the clear with houses and other buildings surrounding it so 
I'm looking to get the max current up as high as possible,

Would going longer on the antenna help maybe 3/8th wave will that effect the 
take off angle, also what would give the best match to 50ohms I'm not that 
clued up on matching networks so want to keep it simple as possible,

I will be able to put a good amount of decent sized radials down 60ft minimum, 

I'm also thinking of hanging a 80m wire down along side the vertical spaced 2ft 
out and feeding it with another piece of coax against the same radial field 
will this cause me any issues ??

I had a trap on a previous inverted L for 160/80 and the bandwidth was terrible 
so thinking this approach might work better,

I'm a newbie to all this so be gentle with me Hi Hi 

Also what is a FCP seem it in a previous topic,
