You should be able to adjust antenna so no tuner is needed. Put as many radials as you can, based on data I've seen, 16 ground radials would be the minimum I would shoot far. Space them out the best you can 360. Length of radials on the ground is not critical, when I laid out my 32 ground radials on my 4BTV I used lengths of 8,16 & 33ft. Make sure to have coax choke close to antenna feed point. Bottom line: do what you can do & make the contacts you can, the band conditions will be the major factor here. I also modified the antenna for operation on 12m & 17m with 1/4w vertical wires - real easy to do - works good. 73 K1WJ David
I wrote all of mine and asked them to vote against it. They already waste time on more important things than a couple of thousand hams who now have buyers remorse - Yeah I'm still a Jack Ass - until my next BS statements - 73 AC7DX
I had 2 MFJ Hamtenna 20m whips - used MFJ-347 dipole mount - up 27ft in the air - used plastic folgers coffee can with 7 turns of my coax (8x) - about 6 inches from feed point. This antenna would in general out perform a Hustler 4btv ground mounted with 32 ground radials by 2 s units day in day out. Used for 18 months - worked well considering it was only 16ft wingspan - 1/2 of a normal 20m wire dipole.
I have also used a single MFJ 20m hamtenna ground mounted - 2ft off the ground with a single 1/4w counterpoise (16.5ft+-) - held up on insulator side 2ft off the ground by tripod. Also had Folgers coax choke 7 turns. Can see a 10m & 20m set up in AZ - pic on upper right - at QRZ.com - under my call K1WJ
Both antenna's (20m) had about 150 khz bandwidth below 2:1 swr - 73 David K1WJ
