Homemade antenna Issue High SWR

[Gunner357]

only if the extra 20ft is faulty or bad connectors as you discovered,

if the extra 20ft is perfect & you don't have cmc on the braid vswr should read a little lower with the longer coax due to more loss in the coax the further away from the feedpoint you place the meter/analyser,

tuning will change when you raise it higher above ground especially if you start near the ground.

am at ch1 1:3 ch20 1:3 ch 40 1:6 it was ch 1 1:4 ch 20 1:1 ch40 1:3

needs shortening a little if you want vswr lower.

I cant, I just make it now..... I dont like doing this way But I just ordered a MFJ tuner That antenna isway to heavy for me to raise and lower to tune

Nothing wrong with the 1.6 to 1.3 SWR.
No tuner needed for that.

What did you order Gunner?
I would most likely tell to cancel, most of those so called 300 watt MFJ tuners are HIGHLY overated!!!! Most will take 100 watts of carrier MAX and 150 watts PEP and that's about it.
Homer is right the antenna is fine otherwise, unless you plan on running one of those "Picky" transistor amps!!!!
Any tube based amp will load that and never care!

Gunner: Also can you reach the bottom section of tubing while standing on the roof??
You can change the tuning from there by shorting or lengthen and inch or so each way and adjust it...You need not do that from the top.
Some guys get way to touchy about the length and get crazy messing with tuning rings etc.
The antenna will work just fine adjusting the bottom section, as long as it's like +/- an inch or 2!
Thus if you wanted a better VSWR "higher" up the band

Those numbers are pretty close.
MFJ rates their tuners the same way the FCC used to rate legal power : by input power to the exciter.

Antennas used to be rated this way too.

Every MFJ tuner manual

MFJ 949E is whats coming It no Biggy if i dont like it Ill sell it.... ..... theres no way I can reach the antenna with out taking it down and its a pain And yes eventually I am running a amp ..... I just want to get this antenna crap finished and start studying to take HAM license exam
