I have been using a Par EndFedz Mk2 Trail Friendly 40/20/10 though using the matchbox from an EndFedz EF-QUAD (with Vibroplex’s blessing) so I could transmit at more than 25W. On all three bands I have very nice SWR - for 20m and 10m around 1.1. For 40m 1.1-1.5. Today I switched over to using the radiator that actually came with the EF-QUAD matchbox - heavier gauge wire and full-size at 40m rather than being electrically-lengthened like the Mk2. And I seem to be getting better receive performance with it. However, I can’t get SWR much below 1.5 on any of the bands, despite the charts that come with the antenna saying it should bottom out at 1.1. By trimming (well for now, folding back on itself) I can move the minimum SWR frequency but I have not been able to make SWR go lower. Everything in the shack is the same. And the house end of the antenna is in the same place. The antenna is at the same angle (perpendicular) to the house. Now, since this antenna is 25’ longer than the other one the far end is in a different place, making this antenna actually further off the ground than the other one. However it also goes closer to trees. It is not touching any branches or limbs but does come within a couple of inches of some decent-sized limbs in a few places. Could that be messing with my SWR?
