I can see your concern:
Having recognised that concern, how would I choose to mitigate it?
- Have the purchase document with you
- Have the spec sheet with you
- Have some form of document from the party you are visiting.
My guess is a device like this you are taking with you to attend some kind of function, maybe a conference or possibly a client. Having something, anything at all, that demonstrates your purpose in carrying this device is to use it in your destination is likely to go a long way towards making whomever sees it in their scanner feel more comfortable.
There is a reasonable chance that somewhere along your way - you will be asked to explain what this thing is by somebody who has little knowledge of RF, and whose sole purpose in evaluating your response is to determine if this is likely in any way to be a threat. recognising this in advance, will help you to have an appropriate response.
Many people in these jobs have some degree of skill in picking up on people who are shifty. People who are nervous. whether they get that from training or just "on the job". So don't be nervous. The most important part about traveling, and making it through security checks, is to not set off internal alarms by any of the security personnel.
When travelling I ALWAYS bear in mind 2 things:
- The person I am talking to is a human being
- You catch far more flies with Honey than Vinegar
Good Luck! (It would be really cool to know how your travel works out...)
