I have a dipole that is 1:1 at both it's main length design frequency and the single fan dipole design frequency underneath it. Each began life 10% longer than design (formulas), one actually had to have a few inches added - and that was soldered when the line was still brand new. The other required shortening in 2" increments. Over a period of two months, the antenna still has "1:1" on those two design frequencies. Checked with reliable equipment besides the MFJ 962D tuner, which now rests on "Bypass" except for higher frequency diversions. This was designed and built for two frequencies only, and performs flawlessly in that respect. So yes, achieving 1:1 SWR is not only possible, but nothing less was acceptable in the specific need I had for that antenna. Jack Virginia Beach |
