>> The NVIS antenna DIY presentation to the club is just over a week away.
>>
>>
>>
>> As we discussed in the NVIS Zoom meeting, the presentation agenda has
>> the following main points:
>>
>> 1. Project Overview
>> 2. Overall Group Progress To Date
>> 3. Individual Antenna Presentations
>> 4. Future Next Steps
>> 5. Conclusions
>>
>> With 5 to 6 individual antenna presentations, we need to be as complete
>> as possible concerning each antenna presentation; yet, as brief as possible
>> to make sure that everyone has a chance to speak. To help this process I am
>> proposing that each antenna presentation address the following points:
>>
>> 1. Chosen Antenna Name/Type
>> 2. HF bands covered
>> 3. Portability for carry (shape/size/weight)
>> 4. Space required for deployment
>> 5. One person installation (Yes/No)
>> 6. Installation details for NVIS configuration
>> 7. DIY project (Yes/No)
>> 8. DIY Issues/difficulty
>> 9. Testing result, if any
>>
>> The idea is to create a spreadsheet containing these points to later
>> provide a quick comparison of antennas. Please consider this approach as
>> work in progress, we can make improvements as we go forward.
>>
>>
>>
>> Thus far, we need to confirm that we will have the following antenna
>> presentations:
>>
>> Todd - Vehicular antenna
>>
>> Alex - AS-2259
>>
>> Ryan - Alpha Delta DX-DD hack
>>
>> Bob - EFHW (DIY?)
>>
>> Don - End Fed Long Wire (kit)
>>
>> Andy - Chameleon End Fed antenna ??
>>
>>
>>
>> If you will send me photos of your antennas, I will make sure they are
>> shown on the meeting slides so that the Zoom audience can view them during
>> your antenna discussions.
>>
>>
>>
>> The plan is that the in-person meeting audience will be able to "touch
>> and feel" and ask questions about antennas in the room.

>>
>>
>> Please feel free to comment on this plan with your thoughts and ideas.
