Generally, no. Because of the high frequencies involved, special coax suitable for microwave use is required to keep the losses low. Several people have asked if they can substitute RG-58, RG-8 or RG-214. These coax types have unacceptably high losses at these frequencies. People occasionally ask about 75 ohm TV/satellite coax as well (RG-62), which is a definite no-go because of the incorrect impedance. Belden 9913 is questionable because of "water piping" problems.

Coax is a standard cable that connects your tv and or cable modem to your wall outlet. Generaly the wiring for tv/broadband is done in coax cabeling called RG-6. The cable has a copper core surounded by a plastic sheathing, this is surounded by a braided outer cover of woven mesh wire and in turn is covered by an outer sheath. First, you need to provision your account (additional $5 per/mo.) for two computers. Contact HarborNet for this. Or you can purchase a small office router.

The coaxial cable is run to a cable modem, which is connected to your computer via a Network Interface Card (NIC) or Universal Serial Bus (USB) port. CableAmerica is your complete ISP therefore no other services are required. However, if you decide to retain your old e-mail services they can be accessed through our CableAmerica network. Many services, such as AOL, are greatly enhanced by CableAmerica's speed.

A What ever you do, do not roll it into a small convenient coil. It will become an RF choke. If you cannot let it lie loose under a seat or in a headliner, wrap it into a yarn-like skein of about 12 to 16 inches, put a wire tie in the center and tuck it under your dash, seat, etc. A Absolutely! High SWR will limits distance and may cause serious damage to your transmitter. The time spent tuning your antenna is time well spent. Don't take the chance.

Garmin and Gilsson seem. These models are discussed in a long thread here. Another shorter discussion starts here. Neoprene and sharkskin cases for the 60C and 60CS are discussed here and here. A great thread on cases for the 76C and 76CS can be found here

You can, and some do, in certain special circumstances. If you're standing somewhere (on top of a building or hill) and want to sense stations at a distance, you can use a directional gain antenna to "warscan" by rotating it on a camera tripod or just aiming it by hand.

Any panel-type antenna whose gain does not exceed 9dBi. Please refer to the WJ MPR Series operations manual for further compliance and operation details and usage information. The MPR cards are, however, a firmware update needs to be performed. Please download the software here. Not only does this include the C1G2 update, but also includes updated algorithms for better overall performance. For non-Gen2 applications, this firmware upgrade is still beneficial.

No, both signals enter the RV on the same coax. Once the signals are inside they are separated with a diplexer, which is supplied with the RCA 3900.

Listen's LT-800 uses a reverse BNC connector (this is required by the FCC). This connector is not readily available. You have two options: 1) cut the cable that comes with a Listen antenna and extend it or 2) order an antenna with extended cable (use part number LA-112). We recommend that you not remote the antenna over 100 feet at 72MHz and 50 feet at 216MHz and use low loss 50 ohm coax.

Many of today's cellular and digital PCS phones are equipped with RF ports which enable you to connect an external antenna to your phone. RF ports may be located on the back, bottom, top or side of your cell phone. Unfortunately some phones have no port that would enable to attach an external antenna to. NMO mounts are used to connect your antenna to your vehicle. Most NMO mounts are installed by drilling a hole in the roof of your vehicle. NMO mounts are typically offered as roof or lip mounts.

The PR-411 and PR-414 will feed two TV sets or one TV set and one FM radio. The PR-414 will also feed an AM Radio and it covers the shortwave AM band as well as the Broadcast AM band. If there are several sets on board, consider using one of our combination power box/amplifiers which will feed up to 8 TV sets. For larger systems and higher performance, consider our PR-420 and PR-422 antennas as used on Merchant Ships, Cruise Liners and by the Navy.

You can connect most phones to an external antenna by using an installable hands free kit that comes with an external antenna adapter. You can also purchase an external antenna adapter that allows you to connect the antenna directly to your phone. Some phones have an external antenna port. Other phones require that you remove your fixed antenna and insert an external antenna adapter to that port. Still other phones have no way to connect an external antenna to it at all.

The MM2211 does not support an external antenna. The MM2211 uses a combination of vertical and horizontal antenna arrays to maximize connectivity.

Answer: You need to use 50-Ohm cable, such as either RG-58, RG-59, RG-8 or RG-8M. For cable lengths greater than 80', you should use RG-8 to counteract signal loss. We sell the following cables:

No; we wanted to make this series of product as simple as possible, Usually the engineers at Alinco think of adding features to the radio, but for these models they started with subtracting the features from the current full-feature HT. We know it's missing CTCSS decode, DTMF encode, external antenna connector, multi-function keypads, wide-band RX coverage, etc, but DJ-S series offers the go everywhere, easy to use, best valued Ham radio equipment ever made.

Only Digital Antenna authorized products may be used with the DA4000SBR, DA4KSBR or DA4000MR, DA4KMR system. Using unauthorized equipment with the DA4000SBR, DA4KSBR system will harm the system, void the warranty and can be detected in the event of a failure.

The sending coil is in Series Resonance whereas the receiving coil is in parallel resonance. A serial gives low impedance, which results in a high current and a high-induced voltage over the coil. Due the resonance, a higher voltage as applied is achievable. This gives a higher transmitting field as without a resonance circuit. The induced voltages will be significantly smaller if you using the circuit out of resonance.

A rotor is not necessary and would not provide any increase in performance. Naval antennas are Omni-directional, which means they see equally well in all directions without being turned.

Omni-directional antennas are commonly used on RV's however at this time our mounting arrangements are designed for use on boats and may not adapt easily to your RV unless it can accept a 1.5 inch pipe mount.

Yes an omni-directional antenna can be used on a house but if fringe reception is required, a directional antenna pointed at the fringe station will give better performance.

Most Point-to-Multipoint Wireless LAN systems use V-Pol (vertical polarization). This allows the use of inexpensive vertical omnidirectional wireless antennas. Higher-density areas are beginning to use more H-Pol (horizontal polarization) antennas for PtMP. Point-to-Point (backhaul) systems may use either vertical or horizontal polarization as long the same polarization is used at each end.

The Airborne 802.11b Wireless LAN Module provides two U.FL antenna connections, which are designed for operation at 2.4GHz with a 50 ohm impedance. Diversity operation is supported when two antennas are employed. An antenna should be selected with the following criteria in mind: Match antenna directionality and radiation pattern to the intended operation - omni-directional or directional,

The solution we found was to carry the usual 18" TV dish and purchase a small tripod (Radio Shack sells them). DirecTV or Dish Network would then be available with as many LNBs as you need (HDTV also). This arrangement also gives the RVer more flexibility in treed areas.

All the antennas on the site have good coax feed to them and we do keep quite a bit of spare length available in the event of a failure. You do not need to bring coax. We even have several extra feet of coax inside the Hamlet entry point so that most of our antennas can be spread out a bit between operating positions.

Absolutely NOT! Please understand that the EDX-2 is a "random length long-wire resonator", and the "Long-wire" antenna starts from the input side of the EDX-2 (feeding-point), not from the output terminal. It resonates the antenna impedance automatically to the length of the wire or mobile whip you have connected to the output terminal.

This varies considerably, so you really need to refer to the email you were sent when you signed up. However, you should be able to get a good idea from looking through the FTP section - particularly the "getting connected" pages.

I can get DB25 extension cables for about $2. I originally planned to use IDE 40-pin hard drive ribbon cables, but DB25's are sturdier, easier to connect and disconnect, keyed (so they can't be connected upside down) and unlikely to be accidentally plugged into something bad on the computer. (Older serial ports used a DB25 plug, but I attach the DB25 plug to the joystick and leave the DB25 receptacle connected to the I-PAC end free, so you can't even accidentally plug one into the serial port).
