| SWR on homebuilt Yagi | rdallen56@charter.net | on 14/6/24 |
| What Coax are you using? If you are using RG-58 or something similar it will cause the high SWR condition. You want something like LMR400. Also in the future please submit questions to tis@arrl.org or call using our phone number. John Digital RF Engineer ARRL Lab |

| Hello Vlad I looked up your records and you still show up correctly on our membership search with all of your credentials, unless this has already been resolved on your account I am not sure what the issue is. I can forward your issue to our IT department if you like. John Digital RF Engineer ARRL |

| IC-M700PRO What are my options? | rajens | on 5/4/24 |
| A directional antenna may help a bit with the noise though I would first try to evaluate if the noise is coming from a specific source such as a powerline. What does it sound like? I don't think you need a new radio. | ||
| Distance between antenna and tower | K4DJW | on 5/4/24 |
| Common consensus is half wave separation, though we recently modelled this with Eznec and the performance isn't too different at 1/4 wave if you can't manage 1/2 wave. | ||
