If you are talking about wireless, no you do not need to worry about that.
An antenna is for radio reception. Some antennas are visible and usually mounted on the front right side fender. Some antennas back in the eighties were used for car telephones and CB radios and were not installed by the factory. Most remote starting features and some burglar alarms also utilize antennas. Some radio antennas were imbedded in the windshield
No. Heat is infrared radiation ("infra" means "lower"). Lower frequency means longer wavelength. All radiation is captured by antennas that resonate at the frequency of the radiation. The "antennas" for visible light are electrons that use the radiation to jump into excited states and cause optical neurons to fire. The "antennas" of heat (infrared) are bigger -- they are molecules that jiggle faster when the radiation hits them. That jiggling is heat.
The big building was visible all the way from house.

The constellation Virgo is visible at latitudes between +80° and −80°.
Not all GPS units require an antenna, but they can be very useful when a stronger signal is required than the GPS unit on its own can provide. Antennas will work at their best when you are in remote locations and when the sky is not visible from your vehicle or place on the ground. http://www.maps-gps-info.com/gp-ant.html
The behavioural approach assumes that behaviour can be observed then copied where as the cognitive approach assume humans have the capacity to process and organise information in the mind. it is less concerned with visible behaviour but more concerned with the thought process behind it. hope this helped. I just learnt about this in class. :)

I believe it does. Most new phones have built in antennas that aren't visible. On older models you have to put out the antenna yourself. This helps on older models.
Growth is visible but development is not visible
