PackTenna PackTenna makes ultralight, portable HF amateur radio antenna systems and accessories. PackTennas are light weight, compact, portable HF antenna systems ideal for operating on the trail, at the campsite, on Field Day, SOTA activation, air travel, or HOA restricted locations. PackTennas use full size wire antenna elements that can be configured in a variety of ways including verticals, dipoles, inverted vee’s and long wires delivering full size antenna performance. The unique combination of backpacking quality hardware, a 10 meter (32’) tall mast that collapses to 26 inches and custom feed points and accessories make this the ideal portable HF antenna system. initially started a few years back around 2005, as I have designed and built the antennas for a fellow Ham radio contesters and DX-ers my entire life. At first, it was a nice thing to do for friends, since I had already worked on designing antennas for Cushcraft Corporation back in 1997. In 2000, I had left CC and started my own Telecommunication business, taking a professional hiatus from designing antennas.
Jackite For 30 years Jackite has designed bird kites/windsocks that beat their wings, banking on the air, soaring across the sky emulating a real bird in flight. Fly off a pole like a windsock and be amazed by the realistic flight. All birds made of tear resistant Tyvek and printed with fade resistant inks. We sell fiberglass telescoping poles and accessories.

Ed's Antennas I am the inventor of the TBJ-1 (US patent 9,608,336), DBJ-1, DBJ-2 and DBJ-UHF (US patent 8,947,313) antennas which are extremely popular among the ham and commercial communications community. Please email me if you wish copies of these patents. We have sold over 30,000 of these antennas in the last 12 years to hams, commercial and government agencies. I have published numerous articles on these antennas in QST and CQ (QST March 2017. QST February 2003 and QST March 2007, CQ Summer 2012). They also appear in the ARRL VHF/UHF Antenna Classics, ARRL Vol 8 Antenna Compendium, ARRL Vol. 3 Antenna Compendium. The proceeds of these antennas go to support my group at UC Santa Cruz -Santa Clara Valley.

Dipole Calculator This calculator uses a "K" multiplying factor value of .975 to adjust for the effect of antenna wire diameter on length which is applied to the free-space half-wavelength equation. This works very well with #18 to #12 wire sizes.
