Description: note to me: computer hutch top shelf silent key item, excellent condition - this was indoor connected to his antenna switch (where it could connect to his Henry Radio 2K-Classic-X transmitter) (if you are interested in the transmitter, contact me, I haven't listed it yet, it's heavy). The clip leads were connected to some ladder line that disappeared into the wall of the ham shack. His tower with a Yagi on a rotator was removed before he died so I don't know where the other end of the ladder line was. I contacted Palomar Engineers to see if they knew anything about what is probably a very early model of their Balun, and their reply said that they never made one with leads like this one .... I'm quite sure this isn't a fake, but it's likely the person answering might be newer at the company - this may be from their very beginnings. Anyway, I think the clip leads were not original to the unit, just the wires. Note to me: Emil - to right of Bin 8 the info below is straight from the company's web site for their current productProduct DetailsCountry/Region of Manufacture: USAType: NEWInput ohms/Output ohms: 50 in, 200 outFrequency Range < 2:1 SWR (MHz): 1.8-61PEP Power Rating (watts): 500/1500Input Connector: UHF SO-239Output Connector(s): Eyebolt/WingnutTransformer Topology: BroadbandHardware Type: Stainless - 1/4"Antenna Compatability: OCF, Zepp, Folded Dipole, LoopThe Bullet-4B-500 and SBullet-4B-1500 are multi-core core baluns with a compact enclosure (looks like a bullet) enclosure that is physically lightweight but electrically robust and easy to transport for your portable loop antenna solution or permanent installation. Halyard hoist at top of balun for convenient attachment point. Input is via SO-239 coax connector and output with side eye bolt output. Choose your model rated 500 or 1500 Watts PEP from 1.8-61 MHz.This transformer requires a feed line choke (see related products) to isolate the coax feed line from the antenna. A coax noise filter at the radio end of the coax is also recommended for best results.Vertical Delta LoopsMulti-band vertical delta loops can be oriented several way but the most popular is to have the “pointy” end at the top (usually a single support) and the lower horizontal ends just out of reach of humans and animals. Best feed point at the top for multi-band use with a 4;1 balun. Cut total wire length to 1005/F (MHz) where F is lowest band frequency of use..Single band vertical delta loops are best fed 1/4 wavelength (246/f(MHz)) from the top point down one side. Vertical delta loops use the same 2:1 baluns as the horizontal loops.NOTE: We rate our Bullet baluns (and ununs) VERY conservatively at 500 watts PEP with a 50% duty cycle. Some manufacturers selling low cost baluns may use a 5% duty cycle for their PEP rating to make it appear you get a higher rated balun for a lower price, but you may in fact be getting be getting less. Their 1500 watts PEP really means 75 watts continuous or 150 watts at a 50% duty cycle compared to our 250 watts at 50% duty cycle. Our baluns typically cover a larger frequency range under 2:1 SWR which make your transceiver happy and probably will last longer with less electrical stress.Remember we over engineer our products, to out perform our competition - just compare the weight of our baluns to theirs and you will know we put much more into our products so you don't have to worry about failure at a critical moment.
