Is it possible with EZNEC to simulate it? It is made of transmission line (partly) Yes or No is enough. I have the DEMO version. 73 Jouko OH5RM Yes, a simulation should be reasonably accurate. The segmentation limitation of the demo version will probably reduce the accuracy some, but you'll be able to get a very good idea of how it will work. Roy Lewallen, W7EL Yes indeed, the simulation verified that my FINAL PLAN is working OK Two very clean resonances at 3.6MHz and 10.1MHz SWR abt 1.3 on both bands Antenna length only 26m instead of normal 41m for 80m dipole. For the stub section I used 0.003m=3mm spacing and 1.5mm insulation on 1mm wire DielC 2.6. Is there any possibility in EZNEC to calculate how long is quarter WL on 10.1MHz with these stub variables? By using transmmission line objects it could have been possible to use the VF of line 0.73. I did run out of segments to simulate tri-band version with additional parallel dipole. All simulation was made in free space and probably needs some minor tuning in real life. 73 Jouko OH5RM |
