In our TV receiving Yagi-UDA antenna array the pipes are hollow. Is there any technical reason behind it ?
Added after 4 minutes:
The TV signal travells in the range of MHZ. now normally, at that particular freq. range the waves propagate throgh the medium in zig-zag fashion upto a penetration depth, from the periphery of the conductor not from the inside.so, inside material are fully, useless.so, it is kept as hollow.
