Just got an advertisement from cycle 24. They have telescoping lengths of 6063 tubing (not as strong as the 6061) that is usually used to make antennas. Great cross-boom material and seemingly inexpensive. Anyone need anything and want to go in on a buy? This place also has saddle clamps for like $1.50 each.<br>
